LBTEK offers CHROMA high-performance bandpass filters with a diameter of 25 mm and a mechanical retaining ring. The bandpass filter only allows complete transmission at the center wavelength, with a blocking range optical density as high as OD5 and OD6. The CHROMA high-performance bandpass filters provided by LBTEK utilize magnetron sputtering coating technology, featuring high transmittance, high blocking depth, and high steepness. In applications with high signal-to-noise ratio requirements, 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 effective signals, resulting in better imaging performance.

Raman Filters

• Center Wavelength: 266 nm-1064 nm
• FWHM: 3 nm, 4 nm, 5 nm, 6 nm, 7 nm
• Stopband Optical Density: OD5, OD6

LBTEK offers CHROMA Raman 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 the incident angle deviates from the designed angle, the center wavelength may shift. It is recommended to use at the designed angle.
