Guide ▶We are also providing bandpass filter with narrow wavelength (model VPF).
WEB Reference Catalog Code/W3119
▶We can provide high transmittance filter for interference application (model YIF).
WEB Reference Catalog Code/W3118
▶We also can supply to custom specifications which are not mentioned on-line or in our catalog
Attention ▶The absorption wavelength range can not be used with high power laser and high energy pulsed laser.
▶There is no coating on both surfaces of the filter and there is a transmission loss of about 10%.
▶Due to the specifications of the glass material of the green filter, you can not obtain a high and sharp transmittance, we recommend using the high transmittance interference filter (model YIF).
