It is commonly used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. The reflecting surfaces of this Prism must be coated with a metallic or dielectric coating. The standard Penta Prism reflecting surfaces are coated with aluminum with Black Paint.

Jenoptik offers high-quality optical components for precise measurement, analysis, structuring and processing using light.

The beam reflection is achieved either through total internal reflection or by mirror coating on the rear surface of the retro reflector . An Incident beam filling the effective aperture, is reflected exactly back on itself.

Penta Prism is a Five –Side prism, It has two important properties, First the image is neither inverted nor reverse while deviated by 90 degree. Secondly, It is a constant deflection device; i.e all the transmitted rays are deviated by the same exact 90 degree. Slight movement of the prism does not effect the true right angle.

Diffraction grating

Corner Cube Retro Reflector are used to reflect light beam back to the direction that it comes from. The reflected beam is always parallel to to the incident beam, and it travels in the reverse direction of the incident beam. This hold true regardless of the angle of incident beam.

Equilateral prisms are normally used as dispersing prisms. As well as standard BK7 prisms, higher index. SF2 and F2 prisms are offered to increase the dispersive power.

Transmission grating

Blazed gratings are optical gratings, which are design in such a way to optimize diffraction efficiency for a specific diffraction order. Although blaze gratings are typically designed for single wavelengths and small diffraction angles, Jenoptik´s blazed gratings can also work at larger angles.

Equilateral prisms have three equal 60° angles and are also referred to as dispersing prisms. Equilateral prisms are used for wavelength separating applications. Optica offers equilateral prisms in both uncoated and anti-reflective versions.

The Protective Al2 coating can be given to the rear reflecting Surface to avoid total internal reflection failure at high incident Angle.

The e²® - PCGs from Jenoptik are the right solution to enhance your laser performances. Besides high diffraction efficiency, low wavefront error, high laser induced damage threshold, the e²®- PCGs are protected against external mechanical damages and dusty due to the fact that the grating structure itself is embedded.

Diffraction gratings are one of the key elements in CPA (chirped pulse amplification) setups of femtosecond lasers. The diffraction efficiency of the pulse compression gratings (PCGs) has a huge impact on your laser performances in terms of efficiency and beam quality.

Echelle grating

Like other optical gratings, blazed gratings are periodic in design, which determines to final diffraction angle. The profile of the blazed grating is a triangular cross section, often called a  sawtooth-shaped cross section. Jenoptik can fabricate blazed gratings with very tight control on the period and the angle of the saw tooth cross section, which results in a high diffraction efficiency in the desired diffraction order.

Application: Telescope Diagonals, Range Finders, Microscope Image Bender, Periscope , Bore Sights And To Make Cube Beam Splitters Etc..

Diffraction grating experiment

The Jenoptik PCGs are custom designed and fabricated into high-purity fused silica guaranteeing high laser damage threshold and thermal stability.

Thanks to more than 25 years of experiences as pioneer in design and fabrication of diffractive micro- and nano-optical elements, Jenoptik can provide excellent diffraction performances solutions for your gratings custom applications.
