Request InfoDelta Optical Thin Film A/SHØRSHOLM, Denmark, Feb. 5, 2018 — A laser attenuator developed by Delta Optical Thin Film AS utilizes an ultrahard-coated, laser optical multilayer attenuator (LOMA) filter. The laser attenuator enables computer-controlled attenuation of a monochromatic light source from 1 to 99 percent within the wavelength region of ~550 to 1000 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. The LOMA filter used in the laser attenuator uses a customized version of the standard linear...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 1/31/2024Quad Band ProductsThe emission filter and beamsplitter quad band solutions from Delta Optical Thin Film extend the company’s offerings to up to four wavelength passbands for multispectral fluorescence...Photonics.com 11/1/2023Interlocked Control SystemThe Lasermet ICS-7 ALF from Lasermet is a compact version of the ICS-7 OEM interlocked control system.
