 OPTICAL DISK, HARTL

 

For demonstrating important principles of optics such as reflection by various shapes of mirrors, refraction through several types of lenses, total internal reflection and dispersion.
The apparatus consists of a satin finished metallic disc about 30cm in diameter, graduated around the circumference in 360. A handle on the back can be used to rotate the disk through 360 in a vertical plane about a horizontal axis perpendicular to the plane and passing through the center of the disk.
The disk is partially shielded by a hood adjustable through 360 degrees. On the hood is a circular plate with slits to allow ray or rays of light to pass and fall on the optical elements. The hood also has a slot for placing red, green and blue filters. The disk face is outlined for various optical elements so that light coming through these slits strikes them at correct angles. The disk is mounted on a heavy tripod base.
A strong source of light for sending parallel rays through the slits and on to the shielding screen is required. Optics and filters are not included.

Cat. No.

3358-01


 ACCESSORIES FOR OPTICAL DISK, HARTL

 

Includes the following glass lenses or prisms. Frosted faces. Thickness 10mm.
Packed in a velvet lined case.
Spherical bi-convex lens, length 85mm
Spherical bi-concave lens, length 85mm
Triangular right angle prism (90-45-45), hypotenuse 75mm
Trapezoidal prism, base 85mm
Semicircular lens, diameter 85mm
Circular lens, diameter 85mm

Cat. No.

3358-05

Note: The optical elements are fixed on the metal disk by means of clamping screws which are provided with the Hartl Optical Disk.


NEWTONS RING APPARATUS

 

For studying interference fringes due to sunlight or monochromatic light.
Consist of a plano-convex lens, diameter 60mm, and an optically polished (worked) flat glass plate mounted on a ring metal pressure frame with three compression adjusting screws for proper centering of concentric circular Newton rings.

Cat. No.

3370-00


 SPECTROSCOPE, DIRECT VISION

 

For quantitative examination of spectral composition of white light, radiant bodies etc.
Comprises a metal draw-out tube of 20mm diameter, with an adjustable slit at one end. The light passing through this slit falls on the prism elements and break up into a spectrum. This can be viewed through an eye piece at the other end of the tube. Fully drawn-out length is 130mm. Supplied in a velvet lined case.

Cat. No.

3372-00


 STROBOSCOPE, HAND DRIVEN, SIMPLE MODEL

 

For optically slowing or completely stopping any object in motion and for measuring the frequency of periodic motion.
Consists of a black metal disk of 250mm diameter with 12 evenly spaced radial slits extending to its edge, an axis hole for mounting a handle and a finger hole. Handle and mounting screw are included.

Cat. No.

3374-00


 SPECTRUM DISCHARGE TUBES

 

To show spectral lines of pure substances. Mercury and helium tubes can be used as sources for experiments on the measurement of wave length of light. The gas pressure used results in well-defined emission spectra.
These are glass tubes about 26cm long, central capillary portion about 9-10cm long with electrodes sealed at both ends and connected to lead wires protected by metal caps. Provided with loops welded to caps for electrical connection. Needs an induction coil 5cm spark, or a suitable transformer. Except for neon and helium, these can not be used as lamps. Length of capillary portion can be varied as required. For intermittent use.
