530DF20 12.7 mm Dia. Protected Coating; Bandpass Filter Protected Coating

The 530DF20 is a Bandpass Filter, a type of optical element designed to transmit light within a specific range of wavelengths while blocking other wavelengths. This filter, sourced from Omega Optical, has a catalog number of 530DF20 and is available for purchase on their official website. The current status indicates that it is in stock, ensuring quick delivery upon order.

The filter is circular in shape with a diameter of 12.7 mm and a thickness of 6.3 mm, making it suitable for a wide range of optical applications. It is made from UVFS MAL-1965, a material known for its optical properties and durability.

The 530DF20 has a center wavelength (CWL) of 530 nm, which is the wavelength at which the filter has its maximum transmittance. The cut-on wavelength is 520 nm, and the cut-off wavelength is 540 nm. This means that the filter starts transmitting at 520 nm and stops transmitting at 540 nm, effectively creating a narrow band of transmitted light.

The filter features a protected coating on both the front and back surfaces. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-term performance and reliability. The coating material used is OME 530DF20, a proprietary coating developed by Omega Optical.

The 530DF20 is shaped as a thin lens, which can be beneficial in applications where a flat filter might introduce unwanted optical path differences. This shape also allows for easy integration into existing optical systems.
