FBH1030-10 Premium Bandpass Filter; Dia:25 mm; CWL=1030nm; FWHM=10nm

The FBH1030-10 Premium Bandpass Filter is a high-quality optical component designed and manufactured by Thorlabs. This filter is specifically engineered to allow light transmission within a narrow band of wavelengths, making it an ideal choice for applications that require precise wavelength selection.

The filter features a circular geometry with a diameter of 25 mm and a thickness of 2 mm, providing a robust and compact design suitable for various optical systems. The base shape is a thin lens, which ensures minimal optical aberrations and high transmittance.

The FBH1030-10 filter is designed to operate at a central wavelength (CWL) of 1030 nm, with a full width at half maximum (FWHM) of 10 nm. This means that it allows light transmission in a range of wavelengths centered around 1030 nm, with a bandwidth of 10 nm at half the maximum transmittance. The cut-on wavelength is 1025 nm, and the cut-off wavelength is 1035 nm, providing a sharp roll-off on either side of the transmission band.

The filter is coated on both the front and back surfaces with a proprietary coating (tho flh1030-10), which enhances its performance by reducing reflection and increasing transmission. This coating also provides excellent environmental stability, ensuring the filter maintains its performance over time.
