(Total 12 Products for What Are The Best Optical Lenses)
The principle of geometric drawing of biconcave lens imaging is the same as that of convex lens. The top of the object is also regarded as two straight lines: one is parallel to the main optical axis, deflects into divergent light after passing through the biconcave lens, and returns the refracted light to the main...
Double-Concave (DCV) Lenses have two inward curved surfaces and a negative focal length. They are used for image reduction and to spread light. Double concave lens is similar to flat concave lens. The focal length is negative, but the light incident in parallel diverges outward. The curvature radii of the two sides of...
Optical dispersive prism optical
Altechna wedge prism, which diverts light to the thicker part. By selecting the appropriate wedge, it is easy to create beam deviations without affecting other beam parameters. If two wedges are used close to the inclined surface, a continuous change in beam deviation can be produced by reversing the wedges. It turns...
The chemical properties of BK7 are very stable, so it possesses scratch resistance and corrosion resistance. Meanwhile special grinding and polishing processes are not required, thereby reducing manufacturing costs. BK7 has a high degree of purity and homogeneity. It is nearly free of bubbles and inclusions. The BK7...
Concave lens is used to correct
The principle of geometric drawing of biconcave lens imaging is the same as that of convex lens. The top of the object is also regarded as two straight lines: one is parallel to the main optical axis, deflects into divergent light after passing through the biconcave lens, and returns the refracted light to the main...

Optical Prisms are
used to redirect light at a designated angle, and its design determines how
light interact with it. When light enters an Optical Prism, it either reflects
off an individual surface or several surfaces before exiting, or is refracted
as it travels through the substrate. Bena offers various...
The reflection inside the prism is not caused by total reflection, because the angle of the incident light at the time of reflection is less than the critical angle, that is, the minimum angle of total reflection, so both reflecting surfaces should be plated as reflecting mirrors; The incident and outgoing surfaces...
High Precision Optical lenses and glass
As a manufacturer of optical mirrors, we recommend that firstly choose the right material and coating material according to the environment of optical mirrors and consider whether the adhesion between optical material and coating material is feasible. For example, the adhesion of gold and silver to optical glass is...
Plano-Convex Cylindrical Lenses is a common cylindrical lenses, it available with positive focal lengths, ideal for laser line, uni-axial magnification, Circularizing the Beam from a Laser Diode and combined with other lenses to form complex imaging systems.We provide custom optical component for laser systems and...
Fused Silica Plano Convex Lenses
Fused Silica Plano Convex Lenses Plano Convex (PCX) Lenses
have a positive focal length, making them ideal for collecting and focusing
light in multiple imaging applications. Bena’s plano convex lenses are available
with various substrates, including Fused Silica, N-BK7, Silicon, N-SF10, Zinc Selenide,
Ge, Calcium...
UV Fused Silica Biconcave Lenses
UV Fused Silica Biconcave Lenses With two concave surfaces, biconcave
lenses have negative focal length, causing collimated incident light to
diverge. and they are ideal for expanding the focal length of an optical
system. Bena’s biconcave lenses are offered with various materials, including UV
Fused silica, ZnSe,...
