At435-20X C 25 mm Dia. Sputter Hard Coated; Bandpass Filter

The At435-20X is a high-quality Bandpass Filter, sourced from the reputable vendor Chroma. This filter is specifically designed for use in optical systems that require precise wavelength selection and blocking of unwanted spectral ranges.

The filter features a circular shape with a diameter of 25 mm, making it suitable for a wide range of optical applications. It has a thickness of 1 mm, ensuring durability and stability within optical systems. The filter is constructed from UVFS MAL-1965 material, a common choice for its excellent optical properties and resistance to environmental factors.

The At435-20X Bandpass Filter is designed to transmit light at a central wavelength of 435 nm, with a specified cut-on wavelength of 425 nm and a cut-off wavelength of 445 nm. This narrow bandwidth transmission profile is crucial for applications that require high spectral purity and rejection of out-of-band light.

The filter is coated on both the front and back surfaces with Chroma's proprietary coating, identified as 'chr at435 20x'. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides mechanical protection, increasing the filter's lifespan and reliability.

The At435-20X Bandpass Filter is designed in a Thin Lens shape, allowing it to be easily integrated into various optical systems. According to the vendor's information, this filter is currently in stock and available for immediate use.
