FLH05633-5 Premium Bandpass Filter; Dia:12.5 mm; CWL=633nm; FWHM=5nm
The FLH05633-5 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, centered at 633nm, with a full width at half maximum (FWHM) of 5nm. This makes it an ideal choice for applications that require precise wavelength selection and rejection of unwanted spectral components.
The filter features a circular geometry with a diameter of 12.5mm and a thickness of 2mm, providing a robust and compact design suitable for various optical systems. The base shape of the filter is a thin lens, which can be beneficial in certain optical configurations.
The coating on both the front and back surfaces of the filter is Thorlabs' FLH633-5, which is specifically designed for this filter. This coating ensures high transmission efficiency within the passband and excellent blocking of out-of-band wavelengths.
The physical data of the filter includes a cut-on wavelength of 630.5nm and a cut-off wavelength of 635.5nm, providing a sharp roll-off on either side of the passband. The catalog number for this item is FLH05633-5, and it can be found on the Thorlabs website, where it is currently in stock.
