The high-performance narrow-band and wide-band near-infrared band-pass filter produced by HB Optical Co., Ltd. has a spectral coverage of 700nm to 3000nm. Ultraviolet bandpass filters are manufactured using ion-assisted deposition (IAD) and plasma-assisted deposition (PIAD), and have a long service life. Most filters are packaged in a black anodized aluminum housing with a logo printed on it, and the arrow marks represent the direction of light transmission inside the filter.

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

"D" in the table represents the outer diameter, and the optional outer diameter is 10mm/12mm/15mm/20mm/25mm/25.4mm

If you need other sizes of near infrared bandpass filters, please contact us. We can provide filters with an outer diameter in the range of 10mm to 25.4mm, as well as other filters in this range.
