Corner Cube Prism has the property that any incident beam will be reflected parallel to itself, regardless of the incident angle. These prisms are ideal where precision alignment is difficult or time-consuming.

Sunday Optics manufacture half penta angle prisms according to customer size and drawing The half penta prism makes the beam turn 45, generally Aluminum coatied and black paint protection Material:H-K9L Size:5-100mm Tolerance:-0.05mm Surface Quality:20-10 Angle Tolerance90% S/D 60-40 40-20 20/10 10/5 Flatness 1/10lambda at 632.80nm Chamfer 0.25mmx45 Angle tolerance
Penta Angle Prism are widely used in laser level, Image system, precision system, and optical area. For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled, we can produce high precision penta angle prism,and make coating according to customer's request. Penta Angle Prism Specifications Material BK7, UV Fused Silica,Sapphire, ZnSe,Caf2,Si,Ge,etc. Size 3mm-380mm Size tolerance +/-0.02mm or customer request Clear Aperture>90% S/D 60-40 40-20 20/10 10/5 Flatness 1/10lambda at 632.80nm Chamfer 0.25mmx45 Angle tolerance
Measuring Principle The internal stress of glass and plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from he polarized lamp will be divided into different units, which produce optical interference phenomenon(ripple patterns) in turn. Under white-light lamp, you can see aubergine ripples, which is caused by the presence of stress. From the observation of colored patterns, you can see stress distribution directly, then evaluate and improve the annealing process. The inspection of plastic molds is more complex as the colored patterns cased by stress is irregular. A similar situation may occur with glass products, which is called stress stretching. For example, a qualified mold will have a large amount of stress released by tension. The role of full-wave plate : When testing glass samples without the full-wave plate, usually only black or gray shadow patterns can be seen. The full-wave plate increases or decreases the full wavelength of a phase difference, thereby forming a colored pattern, which is easier to analyze.
