Achromatic doublet glued lens is an optical design that combines two single lenses. The two lenses are made of glass with different refractive index and dispersion, usually one is crown glass and the other is flint glass. This combination produces better image quality than a single lens. By optimizing the lens design, the focal length is almost unchanged in the whole visible spectrum. In addition to chromatic aberration, spherical aberration has also been well corrected, which is very suitable as a laser collimating lens.
Achromatic double glued lens product features:
Achromatic double glued lens is composed of a coronal glass positive lens with low refractive index and a flint glass negative lens with high refractive index. Different from refractive index and dispersion Σ Compared with the spherical single lens, the glued lens composed of multiple lenses can correct the chromatic aberration and spherical aberration. Achromatic double glued lens is usually used in objective lens system, imaging system, laser measurement system or collimating lens of laser experiment.
Achromatic lenses produced by Borisun Optics mainly cover optical bands: 240-410nm, 400-700nm, 650-1050nm, 1050-1620nm and 3-5μm and 8-12 μm conventional lenses
The dimensions are: Φ 12.7mm, Φ 25.4mm, Φ 50.8mm. Hanzhong Borisun Optics has imported equipment for professional processing and high-precision optical lens. At the same time, we have a completed coating production line, which can complete the optical coating processing of biconvex lens. Welcome to inquire.
