Custom Beamsplitters

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.

Refractive Index 1.56; 300 cps Viscosity at 25°C Norland Optical Adhesive 81 ("NOA81") is a single component liquid adhesive that cures in seconds to a tough, hard polymer when exposed to ultraviolet light. It is recommended as an extremely fast and efficient way to precisely bond optical components or fiber optics. It can be cured in a thin layer between two transparent substrates or applied as a dropto form a bridge between two components. Exposure to UV light quickly cures the adhesive and holds the components in place.The outstanding characteristic of this adhesive is its extremely fast cure. Thin films can be initially set in under 10 seconds and thick films in 20 seconds using the light sources listed below. It is also extremely stable when not exposed to UV light. NOA 81 will not gel up in dispenser tips or cure before you want it to.Typical Properties of NOA 81 Solids 100% Elongation at Failure 25% Modulus of Elasticity (psi) 200,000 Tensile Strength (psi) 4,000 Hardness - Shore D 90 Shelf life of the liquid is at least 6 months from the date of shipment if stored in a cool (5-22° C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.
