Optical density in stop band: OD5, OD6

LBTEK offers CHROMA High Performance Bandpass Filters with a diameter of 25 mm and mechanical retaining rings. The bandpass filters allow only the central wavelength to pass through completely, with an optical density of up to OD5 and OD6 in the rejection range. The CHROMAHigh Performance Bandpass Filters provided by LBTEK utilize magnetron sputtering coating technology, featuring high transmittance, high blocking depth, and steep edges. In applications requiring high signal-to-noise ratios, such as fluorescence imaging, using high-performance bandpass filters can effectively block stray light to reduce background noise while efficiently transmitting the sample's own fluorescence to maximize the collection of valid signals, achieving good imaging results.

LBTEK offers CHROMA High Performance Bandpass Filters with a diameter of 25 mm and mechanical retaining rings. The mechanical retaining rings are marked with arrows indicating the incident direction, with light coming along the arrow direction for easy installation and use. When used at incident angles deviating from the design angle, the center wavelength may shift. It is recommended to use them at the designed angle.
