At its booth Delta Optical Thin Film will be showing its range of custom continuously variable bandpass filters (CVBPFs) for mid-size and full-frame CCD/CMOS detectors. These filters offer very high transmission and are fully blocked in the light-sensitive wavelength range of silicon-based detectors.
A new Laser Attenuator has been developed, which utilises an ultra-hard coated, Laser Optical Multilayer Attenuator (LOMA) filter from Delta Optical Thin Film.
The laser attenuator enables computer-controlled attenuation of a monochromatic light source from 1 to 99 per cent within the wavelength region of ~ 550-1,000 nm. It provides the user with safe, repeatable, and real-time control over the attenuation by combining the LOMA filter with a linear drive, controlled electronics, and dedicated software.
Delta Optical Thin Film has launched several LED and laser bandpass filters optimised for specific LED and laser wavelengths. They combine large angular tolerance with high transmission
Last month Delta Optical Thin Film invited the public to send in their suggestions for a new name for its linear variable bandpass filters for Hyperspectral Imaging. The name it chose was Bifrost
Edinburgh Biosciences and Delta Optical Thin Film announce the release of a new type of laser attenuator that is based on Delta's proprietary linear variable filter technology
