FB9500-500 Dia. 1 in IR Bandpass Filter; CWL=9.50 µm; FWHM=500nm
The FB9500-500 is a high-quality bandpass filter, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This filter is specifically engineered for infrared (IR) applications, with a central wavelength (CWL) of 9.50 µm and a full width at half maximum (FWHM) of 500nm.
The FB9500-500 is a circular filter, with a diameter of 1 inch (25.4mm) and a thickness of 1mm, making it compatible with a wide range of optical systems. The filter is made from silicon sal vil 1957, a material known for its excellent optical properties in the IR spectrum.
The filter's coating is another notable feature. Both the front and back surfaces are coated with the same material, denoted as 'tho fb9500-500'. This coating enhances the filter's performance, ensuring precise wavelength selection and high transmission.
The physical data of the filter includes a cut-on wavelength of 9250 and a cut-off wavelength of 9750. This means that the filter allows light within this specific wavelength range to pass through while blocking light outside this range.
According to the vendor's website, the FB9500-500 is currently in stock, indicating its availability for immediate purchase and delivery. The product's web link is provided for users who wish to access more information or place an order.
