Optical Filters for Fluorescence Microscopy

Wavelength 351-4500 nm; Active Aperture 2-12 mm; Bandwidth 0.3-12 nm; Acousto-optic tunable filters (AOTF) are used to rapidly and dynamically select a specific wavelength from a broadband or multi-line laser source. As the applied RF frequency is varied, the transmitted wavelength changes, “tuning” the wavelength of the beam or image in tens of microseconds or less. An extensive line of AO tunable filters is available for wavelength from the UV through mid-IR, with resolution bandwidths of less than 1nm, with options such as large-aperture imaging filtering and sideband suppression. Fiber-coupled acousto-optic tunable filters devices are available upon request.AOTFs with apertures less than 6 mm are typically used that have less than tens of nm of resolution bandwidth at NIR wavelengths and less than ten nm at visible wavelengths. A quasi-collinear AOTF can deliver < 1 nm resolution bandwidth if operated with highly collimated light. AOTFs with larger apertures (> 6 mm) are a powerful tool for spectral imaging, rapidly and efficiently scanning an entire image in wavelength. This is of use in high-speed applications like hyperspectral imaging, confocal microscopy and on-line process control. The cost of AOTFs increases significantly for very large apertures, but they deliver unmatched speed for time-sensitive multispectral measurements in industry and biotech, approaching real-time video rate spectral imaging.  Gooch & Housego’s acousto-optic tunable filters are manufactured using high quality TeO2 crystals grown in-house, polished and fabricated to rigorous standards, with wavelengths from 350 nm to 4.4 µm in a wide variety of apertures and resolution bandwidths. It is possible to filter images up to 25 mm across, meet exceptionally low driver power requirements or design an AOTF to select and transmit multiple discrete wavelengths.Acousto-optic tunable filters often exhibit light leakage outside the resolution bandwidth of interest, typically at 10-20 dB below peak power. This is due to the response function of the AOTF itself but can be minimized using G&H’s patented techniques. Sideband suppression is available in several models, reducing out of band side lobes by greater than 20 dB relative to the primary beam. The AOTF product family includes application-specific solutions for illumination or excitation wavelength selection, as well as multispectral or hyperspectral imaging. For best performance, we recommend a matched RF driver, including the latest digital frequency synthesizer (DFS) driver technology and random access wavelength control.

Our AR coatings can be customized to your application’s requirements – contact the AMS Technologies experts today to discuss your customized anti-reflection coating solution! Broadband AR CoatingA number of standard broadband processes covering many spectral regions is available that can also be adjusted for your specific requirements, e.g. the coating’s properties can be moved to a number of different bands if required. Some examples of broadband AR coatings: Broadband AR Coatings    Optimized Wavelength Substrate Average Reflection Within Wavelength Band AR 400-700 nm Glass <0.5% AR 400-900 nm Glass <1.0% AR 400-1100 nm Fused Silica <1.0% AR 400-1700 nm Sapphire <3.5% AR 400-2500 nm Sapphire <8.0%   V-CoatingAs a special type of anti-reflective coating, V-coatings improve transmission in a very narrow wavelength range around the design wavelength. This type of coating is called a "V-coating" because the curve of the reflection over the wavelength resembles the letter "V", with a minimum at the design wavelength. Both single- and multiple-wavelength V-coat processes are available for laser and LED applications covering a range from 300 nm to 6000 nm, with maximum reflection of <0.25% per surface at the designated wavelength. Some examples of V-coatings: V-Coatings     Optimized Wavelength Substrate Reflection V-Coat 633 nm BK7 <0.25% V-Coat 1064 nm BK7 <0.25% V-Coat 1550 nm Sapphire <0.25% V-Coat 3300 nm CaF2 <0.25% V-Coat 532_1064 nm BK7 <0.25% V-Coat 532_1064_1550 nm BK7 <0.25% V-Coat 532_633_780_1064_1550 nm BK7 <0.25%   Infrared AR CoatingInfrared anti-reflection coating can be provided anywhere between 0.7 µm and 6 µm on Glass, Silicon, Germanium, Sapphire, Barium Fluoride, Calcium Fluoride, Gallium Arsenide etc. to suit your specification.

The use of lasers as the illumination source for fluorescence applications requires special consideration for the optical path. This special attention centers on the coherent nature of the light, the small beam diameter, the polarization, and the power. There are also circumstances where cone angle and scatter within the system play significantly into the design of the optics. Chroma Technology specializes in the design and manufacture of optical filters and coatings for applications that require extreme precision in color separation, optical quality, and signal purity. Chroma Technology’s portfolio comprises single bandpass and single edge filters, multi bandpass and multi band dichroic beamsplitters, complete filter sets for single band, longpass, shortpass and multi band as well as filter accessories. Laser optics must be designed and made differently from standard widefield filters and mirrors. While it is true that most laser optics will work fine in widefield applications, the inverse is clearly not true, as shown by the different specifications in each case. The differences in design and construction may not be apparent to the end-user in every laser application. However, these differences will be painfully obvious in most experiments if these specifications are not met, especially with more demanding applications such as TIRF, Raman, and multi-photon microscopy. While the entire beam path should be considered carefully, the downloadable “application note filters and mirrors for laser applications” emphasizes the filters and dichroic mirrors used in the beam path. Get in touch with the AMS Technologies optical filter experts today to find out which Chroma Technology optical and mirrors for laser applications can meet the demands and challenges of your project.

Spectral Range 300-2500 nm; Standard and Custom Optical Coatings; Fully Automated E-beam Ion Beam Assisted Deposition (IAD) Technology; High Power Handling; Hard Abrasion Resistant Dielectric Coatings Optical thin film coatings are used to change the spectral transmission and reflection behavior of optical surfaces to produce optical components with desirable spectral properties. Nowadays, almost all optical devices have some optical coating applied onto their optical surfaces. OZ Optics uses all-dielectric coating materials and designs that insure virtually no absorption, low loss and no scattering. OZ Optics specializes in coating high power optical components that are used in a variety of applications and industries, using state-of-the-art fully automated electron beam ion assisted technology for manufacturing. Below is a brief description of the coatings available from OZ Optics. we produce. custom designs and runs can also be produced per customer request – contact AMS Technologies for details. Antireflection (AR) Coatings – Laser Line, Wide Band, Dual Band Coatings:Antireflection (AR) coatings are required to increase light throughput, reduce back reflections and minimize stray light in an optical system over a desired spectral range. Optical elements including fiber tips, parallel plates, lenses, and prisms are all regularly antireflection coated. A large variety of antireflection coating designs are regularly used and available. These include AR coatings for: Major laser wavelengths, Dual-band (DBAR) antireflection coatings, Broadband (BBAR) antireflection coatings Custom designs for user-specified spectral regions. Plate Beamsplitters, Tap Coatings, Partial Reflectors:Beamsplitters are used to split reflected and transmitted light of a given spectral range at a specific ratio and predefined angle of incidence (usually 45 degrees). Examples include 50/50, 70/30, and 90/10 transmission/reflection ratios. This also includes control of the polarization states of the reflected and transmitted beams.Tap coatings are used to transmit light but to reflect (tap off) a small portion of light at usually small angles of incidence (e.g 1.8 degrees). 99/1 and 95/5 are common ratios. These are used in a variety of optical systems to measure and control the amount of light that is exiting the optical device (power monitoring). Longwave and Shortwave Pass Filters (Dichroics):Longwave and shortwave pass (also called edge filters, dichroic filters) transmit and reflect certain parts of the spectral range. These filters are designed and made for a predetermined angle of incidence (such as 0 or 45 degrees) or range of incident angles (eg. 0-20, 35-50 degrees), depending on the optical design of the device used. They are used for a variety of applications that require beam combining and separation based on wavelength.One example would be wavelength division multiplexers (WDMs). These devices are used to combine different incoming wavelengths into a single beam. For example, one could combine 532 nm and 633 nm wavelengths into one beam. Laser Line High Reflectors:High reflector mirrors reflect light over a predefined spectral range. Also, partial reflecting mirrors are made where a fixed portion of the light is transmitted. OZ Optics focuses on coating dielectric high reflectors on custom substrates or on fiber tips for a variety of applications. These coatings feature low absorbance, and high power handling. Typical reflectance is R> 99-99.9 %. Custom Optical Coatings:OZ Optics does custom coatings for a variety of applications.

Together with our supplier Vortex, we are able to design and manufacture custom visible filters with short lead-times for many applications. All Vortex filters are sputtered, meaning they are highly durable. We can provide all common types of filter, like Long Wave Pass (LWP), Short Wave Pass (SWP), Wide Band Pass (WBP) and Narrow Band Pass (NBP). Some Examples: Visible Long Wave Pass Filter for blocking lower visible wavelengths (e.g. below 530 nm). Applications include fluorescence, medical systems, order sorting in spectrometers and scientific instruments. Visible Short Wave Pass Filter for blocking longer wavelengths (e.g. above 730 nm) and transmitting short wavebands. Applications include thermal management (Hot Mirrors) in systems and shortening the ranges of sensitivity of detectors. Visible Wide Band Pass Filter used to block a higher and lower wave band and allow a band (e.g. 550 nm to 600 nm) to transmit. A typical application is to isolate a working band in visible systems using Silicon photodiode detectors or visible cameras. Visible Narrow Band Pass Filter typically used to isolate a narrow wavelength range (e.g. around 530 nm) for use in scientific analysis or LED tidying. Steep Edge 45 Deg LWP Filter for separation of colors at 45° angle of incidence – for example blue reflected, orange/red transmitted. Extended Hot Mirror for 45 Deg Angle of Incidence – a type of SWP filter can be used for an application, where the requirement is to reflect the heat of the near infra-red and allow some visible transmission. We are happy to provide a unique visible filter – designed, specified and manufactured to your application’s requirements. Contact the AMS Technologies filter experts today to discuss your customized visible filter solution!
