What is 580nm longpass filter?
A 580nm longpass filter is an optical edge filter that blocks all light wavelengths shorter than 580 nm and highly transmits wavelengths longer than 580 nm. It effectively cuts off ultraviolet, blue and green light below 580 nm, while allowing yellow-orange, red and near-infrared light above 580 nm to pass through.
What is typical application for 580nm longpass filter?
What is key parameter when choose for right 580nm Longpass filters?
The key parameters to select a proper 580 nm longpass filter include cut-on wavelength accuracy, passband transmission, optical density of the stopband, transition width, substrate material, surface flatness, coating durability, working angle tolerance, size and thickness, as well as environmental resistance to temperature and humidity.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nano-materials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass & Short Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
Other Longpass filters in stock from Liyuan Optoelectronics: LP430 LP500 LP560 LP600 LP650 LP800…etc.
