Our Grating Holder optical bench accessory allows you to choose your own size of grating to cover the aperture in the middle of the holder. This accessory is designed to work with our Basic and Deluxe Optical Benches (#OPTBN-BSC and #OPTBN-DLX).

The United Hartl Optical Disk is a compact apparatus that demonstrates the behavior of optical elements by means of ray paths through clear acrylic models. It consists of a circular 9&rdquo diameter graduated disk mounted on a stand and fitted with

The classic demonstration of spectral lines. Each tube has its characteristic spectrum when energized before a spectroscope.

Equilateral, 45mm sides hollow acrylic prism. Has one hole for adding fluids to study refraction and dispersion. Comes with a funnel and a stopper.

During most of their life, stars are mostly composed of hydrogen and generate energy by converting it to helium. Although other elements are present to give individual stars their &ldquofingerprint&rdquo the lines of hydrogen and helium are

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.

This instrument is an enhanced version of our popular Intermediate Spectrometer.&nbsp Its larger 30mm diameter optics give brighter line images and make precise measurements easier.

An economical, high quality bench set that is excellent value for introductory lens work.&nbsp Features include: 74cm extruded aluminum bench with push-on plastic feet and large easy to read scale, three-position riders accommodate push-in stems of

Jolly's Photometer consists of a piece of aluminum foil sandwiched between two acrylic blocks and two eye pieces on either side of the accessory. These eye pieces allow you to observe the intensity of two light sources that are shining on either

The classic demonstration of spectral lines. Each tube has its characteristic spectrum when energized before a spectroscope.

An oversized set of 6 lenses and prisms designed for mounting on a magnetic chalk or marker board. Lenses are about 8&quot long, so your optics experiments would be clearly visible from every part of the classroom.
