Cylindrical lenses are either plano-convex or plano-concave in form and rectangular in shape. These lenses are used in applications requiring magnification only, such as in transforming a point image into a line image or changing the height of an image without changing its width or vice versa. Therefore serves a variety application, such as slit line detector array illumination, bar code scanning, holography, optical information processing and computer, laser projection.

Zero order waveplates A quarter-or half-wave retarder made from two plates of quartz with their fast axes crossed; the difference in thickness between the two plates determines the retardance. Zero-order retarders provide accurate retardance over a broad range of wavelengths and dance over a broad range of wavelengths and are more durable than single-element retarders. Cemented zero-order waveplates Cemented zero-order waveplate is constructed of two multi-order waveplates with their axis crossed. Thus, it performs as a zero-order waveplate because of the effect of two plates counteracting each other. It has wide temperature bandwidth and wavelength bandwidth properties. Because it is cemented, the dama zge threshold must be considered (about 10mw/cm2) when used. Key features: - double plates - broad spectral bandwidth - wide temperature bandwidth - ar coated Technical capability Material: Crystal quartz Dimension tolerance: +0.0, -0.2mm Wavefront distortion: λ/4 @ 632.8mm Retardation tolerance:
Waveplates Waveplates, also known as retardation plates, are optical element having two principal axes slow and fast, that resolve an incident polarized beam into two mutually perpendicular polarized beams. The emerging beam recombines to form a particular single polarized beam. Retardations plates produce full, half, quarter and octadic-wave retardations. Low order waveplates The properties of low order waveplates are much better than the multi-order wave-plates because of its thinner thickness (less than 0.5mm). Better temperature (38), wavelength (1.5nm) and incident angle (4.5�) bandwidth and high damage threshold make it widely used in common application. Also it is economical. Key features: -thickness: 0.2-0.5mm -high damage threshold -better temperature bandwidth -low cost Technical capability Material:crystal quartz Dimension tolerance:+0.0, -0.1mm Wavefront distortion:/8 Retardation tolerance:/500 Wavelength range:240-2100nm Parallelism:< 1 arc second Surface quality:20-10 scratch & dig Coating:ar/ar coating, r < 0.2% on both surface at central wavelength
The true zero order waveplate means that the thickness of waveplate is very thin (less than 0.1mm) which make the true zero order waveplate excellent in temperature, wavelength and incident angle (about 20) bandwidth. Therefore, it is excellent choice for the highly accurate application. It is cemented with a block of glass which is limited to low and medium power application. Key features: - broad spectral bandwidth - wide temperature bandwidth - wide angle bandwidth - cemented by epoxy Technical capability Material: Crystal quartz / bk7 optical glass Dimension tolerance: +0.0, -0.1mm Wavefront distortion: 8 @ 632.8nm Retardation tolerance: 500 Wavelength range: 400-2100nm Parallelism: < 1 arc second Surface quality: 20-10 scratch & dig Coating: Ar/ar coating, r < 0.2% on both surface at central wavelength
Cube beamsplitters are constructed by cementing two right angle prisms together with the appropriate interference coating on hypotenuse. The absorption loss to the coating is minimal. Transmission and reflection approach 50% (average) though the output is partially polarized.

A polarizing prism can divide incident unpolarized light into two perpendicular lines. Where, P polarized light passes through completely, while S polarized light is reflected at an Angle of 45 degrees, and the exit direction is 90 degrees with P light.
