G052404000 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-100mm Uncoated
This is the G052404000, a 12.7 mm diameter, double-concave lens made from N-BK7 glass, sourced from Qioptiq Photonics. The lens features a center thickness of 1.5 mm and an effective focal length (EFL) of -100 mm, making it suitable for applications requiring strong negative optical power.
The lens's geometry includes a first radius (R1) of -104.41 mm and a second radius (R2) of 104.41 mm, both measured from the lens's center thickness. The lens's inner and outer radii are 0 mm, indicating a symmetrical concave-concave shape.
The lens is made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and wide transmission range. This specific lens is uncoated, meaning it does not have any additional anti-reflective or protective coatings.
The lens is designed to operate at a wavelength of 588 nm. It is spherical in shape, a common choice for its ease of manufacturing and versatility in optical systems.
