39-363 25 mm Dia. Hard Coated OD 4.0 5nm Bandpass Filter; t=3.5 mm 808nm
The 39-363 is a Bandpass Filter with a diameter of 25 mm, sourced from the reputable optical components vendor, Edmund Optics. This particular filter is designed to transmit light within a specific range of wavelengths, centered around 808nm, making it ideal for applications that require narrow-band light transmission.
The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 39-336'. This coating enhances the filter's durability and resistance to wear and tear, ensuring long-lasting performance. The filter's thickness is 3.5 mm, providing sufficient structural integrity for most applications.
The 39-363 features a Cut-On wavelength of 805.5nm and a Cut-Off wavelength of 810.5nm. These values are crucial in determining the filter's transmission properties. The Cut-On wavelength is the point at which the filter starts to transmit light, while the Cut-Off wavelength is the point at which it stops. The Center Wavelength (CWL) is 808nm, indicating the midpoint of the filter's transmission range.
This filter is designed in a Circular shape, a common configuration for optical components due to its ease of integration into various systems. The geometry also includes a Thin Lens shape, suggesting that this filter may have lens-like properties or may be used in conjunction with lenses in an optical system.
