The FB1560-12 is a Bandpass Filter from Thorlabs, a leading vendor in the optical industry. This filter is designed with a circular base shape and a diameter of 1 inch (25.4 mm), making it compatible with a wide range of optical systems. The filter has a thickness of 3.5 mm, providing sufficient structural integrity for most applications.
The FB1560-12 is specifically designed to operate around the wavelength of 1560 nm, with a full width at half maximum (FWHM) of 12 nm. This makes it ideal for applications that require narrowband filtering around this wavelength. The filter's cut-on wavelength is 1554 nm, and the cut-off wavelength is 1566 nm, providing a relatively steep transition between the passband and the blocked wavelengths.
The filter features a thin lens shape, which can be beneficial in certain optical systems. The front and back of the filter are coated with the same coating, identified as 'tho fb1560-12'. This coating is designed to enhance the filter's performance at the specified wavelength.
According to the vendor's website, the FB1560-12 is currently in stock, indicating its availability for immediate purchase and delivery. The product's web link is provided for further details and specifications.
