84-734 50 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=5 mm 1050nm

The 84-734 is a high-performance Shortpass Filter, sourced from the reputable vendor Edmund Optics. This filter is designed with a circular base shape and a diameter of 50 mm, making it suitable for a wide range of optical applications. The filter boasts a thickness of 5 mm, contributing to its robust construction and overall durability.

The Shortpass Filter is designed to transmit wavelengths less than or equal to 1050 nm, while effectively blocking wavelengths greater than this value. This specific cut-off wavelength is crucial in various applications, such as fluorescence microscopy, where it helps to eliminate unwanted long-wavelength light.

The 84-734 filter features a hard coating on both the front and back surfaces, enhancing its resistance to scratches and other forms of damage. This coating also aids in maintaining the filter's performance over time, ensuring consistent optical transmission.

The filter's geometry is defined as a Thin Lens, suggesting that it has been designed to minimize optical aberrations and distortions. This feature is particularly beneficial in precision optical systems where high image quality is paramount.
