This excellent instrument is easy to set up and easy to use and is designed for students to make precise measurements. This unit features high quality 22MM optics, a built-in illuminated auto-collimator for fast set up, a 17.8 cm diameter divided circle with clear gradations, a double-ended vernier…

Made from Plate Glass, with carefully ground and polished optical survaces, and cleanly ground edges, these lenses feature a diameter of 38mm - 125mm and focal lengths from 50mm - 500mm.

The classic demonstration of spectral lines. Each tube has its characteristic spectrum when energized before a spectroscope. These tubes acquaint students with the spectra of common gasses in their pure form as well as for demonstrating wavelength. The glass tubes are 25 cm long with the capillary…

Constructed of clear acrylic with highly polished surfaces, these prisms are ideal for projecting a clear, sharp spectrum. Set of Right-Angled Prisms consists of 25mm, 50mm, and 75mm long prisms.

This is an excellent and economical set for introductory ray optics. The laser ray box projects one, three, or five parallel bright beams and is equipped with a momentary switch for safety. A vinyl template with a degree circle and a linear scale forms the optical disk, and the set includes seven…
