The dielectric multi-layer coating offers a high optical performance. Provides a wide range of visible color quality green, blue, red, yellow, magenta and cyan.

◦The switching from reflecting and transmitting is steep; it is usable as a wavelength separation filter.
◦Easy to be used as a variable wavelength filter by changing the angle of incident.
◦Able to choose from a range of the six fundamental colors, fits perfectly for color vision experiments.

▶B270® is a registered trademark of SCHOTT AG Inc.
▶Different size, wavelength and deviation ratio not mentioned on-line or in our catalog are available as custom products upon on request.
▶For a suitable filter holder, please contact our Sales Division.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶Do not use filter with high power laser and high energy pulsed laser. We can provide pulse laser use dichroic filters, please contact our Sales Division.
▶If the reflecting light of the filter is used, the transmittance and the reflectance value may change in accordance to the angle of incident.
▶The color may appears different than expected at 45 degrees angle of incidence, therefore to obtain the sharp color, please use it a 0 degree.
