Bandpass filter
A type of optical filter that transmits any specific wavelengths and blocks out other unnecessary light.It is possible to set any central wavelength (transmission wavelength) from the ultraviolet to infrared range, and create a custom setting for the half-width, stop band, etc.It has been used for analytical equipment, medical equipment, sensors, exposure machines, etc. Infrared Bandpass Filters Near-infrared to far-infrared bandpass filters are optical components that are widely used in optical communications,industrial equipment, medical equipment, gas concentration sensors, etc.We receive many requests for wavelengths such as 1550nm, 1064nm, 2.75㎛, 3.3㎛, 4.25㎛, and 4.75㎛.We have an infrared spectrophotometer to evaluate down to 20μm.This product is also useful in the security…
