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-10351 Accessory Set for Interferometer

This accessory set for the interferometer U10350 consists of a vacuum cell for determining the refractive index of air and a glass plate on a rotatable holder for examining the surface quality of optical components (Twyman-Green interferometer).

TEL-20500 Vacuum Hand Pump

Simple mechanical air pump for evacuating small containers; equipped with a pointer manometer, ventilation valve, two hoses (long and short) and six connecting adapters.

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
