Bi convex lenses have two outward curved surfaces, normally the two surfaces have same radius of curvature, with finely polished. Bi convex lenses have positive focal length, so they are used for 1:1 imaging and in multi-element systems. Bi convex lens is a good choice when the object and image are at equal or near equal distance from the lens. Bi convex lens spherical aberration is larger than that of plano convex lens, so focal length may not gather at one point. We manufacture bi convex lenses with optical flint glasses, crown glasses, UV grade fused silica glass and infrared glasses. AR coating is applied to the surfaces of bi convex lenses for enhancing transmission.

Plano convex lenses are flat on one side and with a precision convex surface on another side. Plano convex lenses are used to focus, collect and collimate the light to one point. It’s ideal choice to focus light to a single point. The lenses are useful in lasers, detectors, collimators, condensers and fiber optics. Our plano convex lenses are polished to tight tolerances minimizing wave front distortion. The lenses are offered with anti-reflection coatings for different wavelengths including visible, UV and infrared wavelengths. Competitive prices and fast delivery are available from us for the lenses. Our production capabilities: Substrate Optical glass N-BK7, N-BAK4,UV fused silica,silicon,sapphire, etc. Diameter available 1.5mm to 800mm Tolerance +/-0.02mm Focal length tolerance +/-1% Thickness tolerance +0/-0.05mm Surface quality 40-20 or better Irregularity Lambda/2 or better Centering 1 arc min or better Chamfer Protective chamfer Coating Anti-reflective coating for visible, NIR, UV and infrared wavelengths or no coating

Plano-concave lenses are thicker at the edge than in the center and flat on another surface. Plano concave lens (PCV) has negative focal length. So the lenses are used to bend parallel input rays so they can diverge from one another making them useful for beam expansion and image reduction application. We offer plano concave lenses with anti-reflection coating, which markedly improves the transmission efficiency. AR coated plano concave lenses are widely used in a lot of optical imaging systems. Custom Made capabilities: Material N-BK7, UV fused silica, JGS1,N-SF11, Silicon, Germanium, etc. Diameter available 1.5mm to 700mm Tolerance +/-0.05mm Thickness tolerance +/-0.05mm Surface quality 20/10 or better Surface accuracy Lambda/4 or better Centering 1 arc min Chamfer protective Coating anti reflective coating for visible, UV, infrared wavelengths and reflective coating for the concave surface, mirror coating

The core principle behind the use of micronized wax in leather processing is that it migrates to the leather surface during the coating and film-forming process, forming a micron-scale waxy protective layer. This reduces the coefficient of friction, enhances abrasion and scratch resistance, improves the hand feel, and boosts water-repellency and anti-adhesion properties.‌‌ Film Formation, Migration, and Surface Enrichment: During the drying or film- forming stage of leather finishing agents, micronized wax migrates to the surface due to differences in compatibility with the system, precipitating as fine crystals to form a “wax-coated” surface layer. ‌Lubrication and Scratch Resistance‌: The low surface energy of wax significantly reduces external contact friction, causing potential scratches to slip away rather than penetrate, thereby improving scratch resistance, abrasion resistance, and resistance to polishing. ‌Hand Feel Control‌: It provides a smooth, rich, or slightly velvety feel while avoiding stickiness; certain waxes can also adjust the finish to a matte or high-gloss effect.
