67-290 25 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=3mm 1200nm
The 67-290 is a Traditional Coated Shortpass Filter, designed and manufactured by Edmund Optics. This filter has a diameter of 25 mm and a thickness of 3 mm, making it a robust and compact solution for various optical applications. The filter is designed to pass wavelengths of 1200 nm and below, while effectively blocking wavelengths above this cutoff frequency.
The 67-290 filter features a Base Shape of Circular, ensuring easy integration into circular optical systems. The filter is made from UVFS Mal-1965 material, a high-quality optical material known for its excellent transmission properties and durability. The filter's coating, both on the front and back, is Edmund Optics' proprietary EDM 67-290 coating, which enhances the filter's performance and longevity.
The filter's geometry, with a diameter of 25 mm and a thickness of 3 mm, allows for easy mounting and alignment in various optical systems. The physical data of the filter, with a cut-on wavelength of 0 nm and a cut-off wavelength of 1200 nm, provides a clear understanding of its operational range.
