fresnel lenses
Specification: according the request of the customer
Detail: Fresnel lens can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances. Fresnel lenses were later produced, being used for automobile h...

rod lenses
Specification: according the request of the customer
Detail: Rod Lenses are generally used as light pipes. Its optical principle is similar to fiber optics where light can be transmitted from one end to the other with relatively small leakage. Rod Lenses can be used as Cylindrical Lense...

beam splitters
Specification: according the request of the customer
Detail: Beam splitters: When a light beam is incident onto a surface inclined at an angle of incidence to the incoming beam, the reflected and transmitted light becomes partially polarised. This can be resolved into two components ...

achromatic lenses
Specification: according the request of the customer
Detail: The achromatic lenses can be used to collimate and focus laser beams. They can also be used for high-quality imaging on-axis. It alsocan eliminate spherical aberration and reduce other optical aberrations co***red to a simple ...

parabolic cylindrical lenses
Specification: according the request of the customer
Detail: Parabolic cylindrical lenses: Material: Optical Glass Diameter Tolerance:+0.0/-0.05mm Thickness Tolerance: ±0.1mm Surface Quality: 20-10 Centration: <3arcmin Clear Aperture: >90% We will do according to t...

off-axis with angle cylindrical lenses
Specification: according the request of the customer
Detail: Off-axis with angle cylindrical lenses: We will also do according to the specifications such as size, structure, material, surface treatment and so on that the customers required. We supply them with good quality and low pr...

right angle prisms
Specification: according the request of the customer
Detail: Right angle Prisms are available in both Laser Quality and Analytical Quality polish designated as LQ (Laser Quality) and AQ (Analytical Quality). Right Angle Prisms are a type of 45-90-45 degree prism typically used to bend a...

roof prisms
Specification: We will also do according to the specifications such as size, st
Detail: Roof prisms also called amici prisms or right angle roof prisms, do two things: invert the image and bend the line of sight through a 90° angle.They are excellent as prism diagonals in optical systems, because they erect the ...

penta prisms
Specification: We will also do according to the specifications such as size, st
Detail: Penta Prisms is a five-sided prism. It reflects light rays through a 90° angle by two reflections and does invert or revert the image. The reflecting surfaces are aluminized. Slight movement of the prism does not affect the t...

dove prism
Specification: We will also do according to the specifications such as size, st
Detail: Dove prism is a type of reflective prism which is used to invert an image. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emer...
