Features

• A filter that extracts light in a specific wavelength range.
• Very high transmittance is achieved in the transmission band.
• A short distance from the transmission band ca***s a steep drop, with little transmission near the transmission band.
• Since a dielectric multilayer film with low absorption is ***d, the transmittance is high and the specified wavelength can be separated efficiently.
• Since the interference filter is fixed to the metal frame, it is easy to fix to the holder and handle the element.
• Filters can be selected from a number of wavelengths ranging from 325 nm ultraviolet to 1064 nm near-infrared.
• An interference filter (VPF) with a wider cutoff band is also available.
• * The characteristics of the interference filter dep*** on the incident angle. When the angle is tilted to the optical axis, the center wavelength moves to the short wavelength side, and the transmittance also decreases.
• * Enter a parallel beam or a light close to the parallel beam at 0° to the optical axis.
• * The narrower the half-width, the greater the angular dep***ency.
