Michelson's interferometer
ISE-8510PS
Understanding the wave nature of the light to measure the interference pattern from Michelson interferometer and calculate the wave length of light.
Michelson Interferometer is a precision instrument capable of measuring the wavelength of visible, monochromatic light
A measurement cuvette set in the beam path of a Michelson interferometer can be evacuated or filled with CO2. The refraction indexes of air or CO2 are determined through the assessed modification of the interference pattern.

Absortion and Emission
ISE-5821
Absorption spectrum
With the white light LED and the provided optical grating the spectral distribution of the absorption spectrum of the fluorescent filter can be observed on the optical screen. The absorption spectrum is imaged by means of the lenses to the optical screen. The emission of the LED is collimated by the lens and passes the fluorescent filter. The white LED mainly consists of red, green and blue lines and serves as spectral lamp in this concept.
Refraction of light ISE-5822
Refraction on plates
When a beam passes a transparent plate a particular kind of deflection occurs, it is shifted parallel with respect to the incident beam. This parallel offset depends on the thickness and angle of incidence of the beam. The plate is mounted on a turn table as part of the swivel unit (6). The rotatable arm is turned into the zero position without the plate. By turning the table different angles of incident can be set and the deviation can be observed by the crossed hair target

Diode pumped Nd:YAG Laser
ISE-5862
The principles of the generation of frequency doubled light will be explained and simultaneously the possibilities of non linear optics learnt in this experiment. The understanding of non linear optical effects is very important for laser technology, since the processes of generation of short pulses are also based on non linear effects. Within the experiment the phase matching condition will be presented and analysed.
The efficiency of frequency doubling will be determined and hints for an optimized conversion rate will be evaluated in the experiment. For the first time the frequency doubling can be followed up in an impressive manner by a practical experiment. The fundamental wave is generated by a diode laser pumped Nd:YAG laser with an open resonator structure. The non - linear crystal is placed simply into the resonator and suddenly green light appears. Furthermore also the mode structure of the Nd:YAG laser becomes visible and shows a great variety of transverse modes. By introducing an adjustable iris into the cavity the number and kind of modes can be controlled and reduced down to TEMoo. By using the "Red 660 nm" option the Nd:YAG laser is operated at 1.3 µm and a special cut KTP crystal allows the frequency doubling into the red part of the spectrum.
Lasers which emit light in the short wavelength spectral range are expensive and not sufficiently reliable for many applications. A more economically way to generate such radiation is achieved by frequency doubling.
Basic Optics System is easy to use, affordable, and ruggedly designed for both geometric bench optics and table ray optics investigations. Large 50 mm diameter optics components are mounted in protective holders that snap directly onto the aluminum track, and they are easy to slide and reposition. Built-in metric tape makes measurements of image and object distances quick and accurate for both lenses and mirrors. The versatile Light Source doubles as a table-top ray box, for studies in reflection, refraction, color addition, and Snell's Law. All the components (except the track) fit in the included custom protective foam storage box.
