CCD Line Camera Accessories

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!

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.

 0.7-6.0 µm; Transmittance >65%->85%; FWHM 42-190 nm; Diameter 25 mm; Thickness 0.5 mm; Surface Quality <60-40 Scratch-Dig  Vortex designs and makes a wide range of IR filters with center wavelengths from 0.7 µm to 6.0 µm. While traditionally thermal evaporation has been used for IR filters, Vortex IR filters are deposited by sputtering using the supplier’s “Rockard”© technology.  Sputter deposition has a process energy approximately three times that of thermal evaporation, leading to the filters’ densely packed structure. This technology ensures the following superior environmental and optical properties: Highly durable coatings suitable for the toughest environments Extremely low temperature shift Reduced passband ripple for even response High blocking efficiency to increase signal to noise ratio All IR filters are sold as 25mm diameter, 0.5mm thick and exhibit high angular tolerance, extremely low change with temperature and very high resistance to thermal shock.  AMS offers Vortex’s wide range of ‘standard’ narrow band IR filters for detection of common gases, chemicals and materials.
