TEL-10350 Interferometer
This equipment set comprises high-grade optical components mounted on a heavy, rigid base plate for precise and reproducible measurements. The large optical components permit a generation of clear and well-defined interference patterns in daylight. The reflective observation screen has an adjustable inclination. Pre-defined component positions allow quick rearrangement to ensure extremely rapid preparation for the various experiments. The equipment set includes a stable plastic box for storing the mounted and adjusted interferometer as well as the laser base plate. A He-Ne laser is required.

TEL-41610 Metrological He-Ne Laser
Laser light can be modulated by varying its intensity. This laser is capable of up to 15% intensity variations at rates up to 1 MHz. The increased brightness can also help students make better holograms. Small movement or vibrations are less likely to blur the picture with a shorter exposure time.
- Beam can modulate from 85% to 100% of full power
- Accepts modulation signals ranging from 50Hz to 1MHz
- Effective signal transmission up to several hundred feet. With collimator and detector transmission range increases to thousands of feet
- Miniature phone jack accepts audio input signals at l00mV peak-to-peak level and 8KΩ impedance
- Two-year limited warranty
