Blue Filter 50mm 390nm

BLF-50S-390B

A filter that transmits a specific wavelength at green from blue, and cuts off other wavelengths in the visible range. It is used to select blue or green wavelength from a light emission or select a specific wavelength from multi-wavelengths.
◦A selection of different type of main wavelength and bandwidth from 370nm to 550nm.
◦To select a wavelength from a large bandwidth light.
◦By insertion of the filter into microscope or CCD camera will provide better contrast in a vision experiment.

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, please contact our Sales Division with your request.
Remark -
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).
