Spectrogon manufactures infrared filters and windows with high transmission, high rejection outside the passband, while maintaining excellent coating uniformity for thermal imaging and gas detection applications such as cryogenically cooled IR detectors and uncooled microbolometers. Our filters and windows range in dimension from Ø6.0 to Ø200.0 mm with dicing capabilities down to as small as 1.0 × 1.0 mm.

Introducing Hamamatsu’s new reflector package for mid-infrared (MIR) LEDs. Output and dispersion have been challenges for LEDs, but now the reflector package effectively doubles the radiant flux within the light path and heavily condenses the dispersion. Users will now benefit from longer path lengths and higher sensitivity, while still enjoying the low power consumption and long lifetimes of LEDs.

Bristol Instruments’ popular 871 system measures laser wavelength at a sustained rate of 1 kHz, the fastest available. It also measures wavelength to an accuracy as high as ±0.0001 nm. By combining proven Fizeau etalon technology with automatic calibration, the most reliable accuracy is ensured for the most meaningful experimental results.
