Overview

High performance narrowband and broadband ultraviolet bandpass filters produced by Huibo Optics, with a spectral coverage range of 200nm to 380nm

Product Details

High performance narrowband and broadband ultraviolet bandpass filters produced by Huibo Optics have a spectral coverage range of 200nm to 380nm. The ultraviolet bandpass filter is manufactured using ion beam assisted deposition (IAD) and plasma assisted deposition (PIAD) processes. The filter film layer is a high-density hard film, ensuring a long service life.

The filters we provide have ultra-high cutoff background depth, which can significantly improve the system's signal-to-noise ratio.

Most filters are packaged in a black anodized aluminum shell with markings on the shell, with arrow marks representing the direction of light transmission inside the filter.

365	10	≥35	D x 6
380	8	≥35	D x 8
394	10	≥45	D x 6
Center wavelength deviation (nm)		± 20% of nominal half peak width
Half peak width deviation (nm)		± 20% of nominal value
Outer diameter tolerance (mm)		±0.1
Thickness tolerance (mm)		±0.2

The "D" in the table represents the outer diameter size, with selectable outer diameter sizes of 10mm/12mm/20mm/25mm/25.4mm
If you need other sizes of UV bandpass filters, please contact us. We can provide filters with outer diameters ranging from 10mm to 25.4mm, as well as other shapes of filters within this range.
