Deposition Sciences Inc.
provides long-wavelength infrared (LWIR)
bandpass filters that operate at temperatures between ambient and 10 K. The thin-film
coatings are manufactured via proprietary physical vapor deposition with the ion-assist
process, making them durable and robust. They feature precise band edge placement
for critical sensing applications. The filters are suitable for use in imaging sensor
filters, order-sorting filters, thermal and/or night vision tasks, and forward-looking
infrared optics. Substrates including germanium, silicon, zinc sulfide, zinc selenide,
quartz, sapphire and polymers are available, depending upon the customer’s
wavelength requirements. Multispectral filters can be provided when multiple filters
are needed on a single substrate. Sizes from a few millimeters to >50.8 mm in
diameter can be provided.
