8. Cylindrical Lenses
Cylindrical lenses can transform a point of light into a
line image. Plano-convex, bi-convex, plano-concave, bi-
concave and meniscus cylindrical lenses range from 5
mm to 350 mm, depending on configuration.
Range Of Work: 5 mm -- 350 mm arbitrary shape.
Surface Quality: 60/40, 40/20 scratch and dig.
Dia.L/H Tolerance: +/- 0.05 mm.
Bus-bar Depth of Parallelism: 0.02mm.
9. Aspheric Lens
Main Applications: increasing the relative aperture of the optical system, widening the angle of view field,
and improving the uniformity of illuminance, simplifying the structure of a system. These lenses are
widely used in illuminating apparatus and stage lighting units of middle grade or high grade that require
reflection, light gathering, magnification.
Lens Type: paraboloidal lens, hyperboloidal lens and
Diameter: 10 mm -- 300 mm.
Precision and Diameter: <0.01mm.
10. Fresnel Lenses (Thread Lenses)
These lenses are widely applied to improve the luminance of image edge and uniform the luminance
in stage lamp systems.
Lens type (Diameter): 50 mm, 75 mm, 80 mm, 100 mm, 120 mm, 150 mm.
Material: low-coefficient pressure glass hot-pressed.
