DAHENG OPTICS convex array lens elements

Diameter: 25.4, 12.7 mm
Wavelength: 450 nm - 1,100 nm

... infinitive, the lens is plano- convex. Similarly, there are lenses that are biconcave, equi-concave and plano-concave if the lens surface is concave. A lens with one convex ...

Diameter: 10 mm - 100 mm
Wavelength: 450 nm - 1,100 nm

... the lens. The optimum case is where the object is placed at infinity (regarded as parallel rays entering lens) and the image is on the focus, which has infinite conjugate ratio, i.e. object distance/image distance. The ...

Diameter: 6 mm - 50.8 mm

... Similar to plano- convex lenses, biconvex lenses also have a positive focal length and can focus parallel light beams. Since both the front and rear surfaces of a biconvex lens are convex spherical surfaces ...

Diameter: 12.7, 10, 50.8, 20 mm
Wavelength: 200 nm - 2,500,000,000 nm

... of 800-1100nm), and they are applicable to most imaging applications. The GCL-0108 series of UV-Grade Fused Silica Plano- Convex lenses are uncoated. The UV fused silica has better homogeneity and a lower coefficient of thermal expansion ...

... Cylindrical lens focuses light only in one dimension. It can also transform a point image into a line image or charging the height of an image without affecting its width. There are two circumference shapes, rectangular and circular. ...

Diameter: 30 mm

... • The lens is pre installed in a metal housing with an outer diameter of 30mm, without external threads • The lens eccentricity has been adjusted and fixed with adhesive, with centration ≤ 0.04mm ...
