Bandpass filters in the near-infrared to far-infrared region are optical components that are widely used in optical communications, industrial equipment, medical equipment, and gas concentration sensors.
We have received many requests for wavelengths such as 1550 nm, 1064 nm, 2.75 μm, 3.3 μm, 4.25 μm, and 4.75 μm.
We also own and evaluate an infrared spectrophotometer used for evaluation in the infrared region.
It is a product that plays an active role in security such as heat detection, infrared sensor, and gas detection.
