Product description

The K9 shortpass filter is designed to effectively block wavelengths above 305 nm while allowing shorter wavelengths to pass through with high transmittance. With a central wavelength of 305 nm and a transmittance of 90%, it is ideal for applications requiring precise light filtering in fluorescence microscopy and other optical systems. The filter’s surface quality of 40/20 ensures minimal distortion, making it suitable for high-resolution imaging applications.

Key Features

  • Transmittance of 90% ensures high light throughput for optimal performance.
  • Shortpass filter type effectively blocks unwanted longer wavelengths, enhancing image clarity.
  • Surface quality of 40/20 minimizes distortion, maintaining image integrity.
  • Customizable options available for OEM, ODM, and OBM support.
  • Clear transparent color with a clear aperture of 80%~95% for efficient light passage.
