Appliance parts


1st shelf (above)

The elements which are showcased here were used by Vilnius university department of Quantum electronics in 1970 – 1995.

1. Optical fiber.
2. Dielectric mirrors.
3. Colored light filters.
4. Nonlinear crystal – an optical element with special features, which allows to extract the full range of colors from monochromatic laser radiation.
5, 6, 7. Prisms – optical elements that refract light
8, 9. Cuvettes – optical “containers“ to hold liquid and gaseous laser substances.
10, 11. Lenses
12. The active medium plate of the laser. “Accurate“ laser light is generated in this substance.
13. Reflectors – optical elements used in constructing lasers heads.

Optical elements allow the change of light. Their operation is based on the phenomena of light physics – refraction, scattering, reflection, diffraction, interference, absorption and complicated non-linear physical effects. Optical elements can vary since various transformations are needed to perform with light.

2nd shelf (middle)

The mechanical assemblies which are showcased here are manufactured by “Standa“ in 1989.

1. Dye laser used by “Eksma“, 1989.
2. Laser resonator’s rear view mirror retainer. Vilnius University, around 1980.
3. Precision turn assembly with diffraction grating from a laser amplifier. Vilnius University, 1985.
4. Multicolor laser’s “TOPAS“ motorized mechanical assembly. “Šviesos konversija“, 1993.
5. Precision mechanical assembly. “Šviesos konversija“, 1993.

Lasers merge two branches of precision engineering: optics and mechanics. Optical elements „work” with light, and mechanical units allow them to be properly mounted and controlled with great precision. The accuracy of the displacement setting can be as high as one micron or even a fraction of it, and the angle setting can be as much as a fractional second.

3rd shelf (bottom)  

1. Three-coordinate shift table.
2. Kinematic mirror retainer.
3. Extremely accurate kinematic mirror retainer.
4. General purpose optic element retainer.
5. Optical compatibility node.
