Delta Optical Thin Film

Delta Optical Thin Film

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.
