FL441.6-10 Dia:1 in Laser Line Filter; CWL=441.6 +-2nm; FWHM=10 +-2nm

The FL441.6-10 is a bandpass filter developed by Thorlabs, a leading vendor in the optical industry. This filter is specifically designed for use with laser systems, offering a narrow passband that enhances the system's performance and precision.

The filter has a center wavelength (CWL) of 441.6 nm, with a full width at half maximum (FWHM) of 10 nm, providing a tight passband that allows for the efficient selection of specific wavelengths. The CWL is the wavelength at which the filter's transmittance is maximum, while the FWHM is the width of the passband at half the maximum transmittance.

The FL441.6-10 is circular in shape, with a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm. This compact design ensures easy integration into various optical systems. The filter is made from soda lime ru clear, a material known for its excellent optical properties and durability.

The filter's coating is another critical feature. Both the front and back surfaces are coated with tho fl441.6-10, a proprietary coating developed by Thorlabs. This coating enhances the filter's performance by reducing reflection and increasing transmittance.

The physical data of the filter includes cut-on and cut-off wavelengths of 436.6 nm and 446.6 nm, respectively. These values represent the wavelengths at which the filter starts and stops transmitting light.

In terms of shape, the FL441.6-10 is designed as a thin lens, further enhancing its functionality and compatibility with various optical systems. The filter's catalog number is FL441.6-10, and it is currently in stock, according to the vendor's website.
