Equilateral prism glass AM0972
Prisms are essential tools for teaching about light refraction and dispersion and come in a variety of shapes and sizes. • size: 2.5 x 10 cm
Set of prisms QH2079
The set contains 8 optical accessories: • flat-convex lens 4 x 8 x 1 cm • right-angled triangular prism 6 x 6 x 1 cm • double-convex lens 4.5 x 13 x 1 cm • double-concave lens 5 x 13 x 1 cm • convex-concave lens 4.5 x 13 x 1 cm • flat-concave lens 1 x 6.5 x 1 cm • convex-flat lens 1 x 6.5 x 1 cm • rectangular prism 2 x 13 x 1 cm • 13 cm plastic dial with degree markings
A set of acrylic prisms and lenses with magnets encased for easy fastening on a magnetic board. The elements can be used to explore the nature of light (refraction, dispersion, internal reflection). The plastic dial with degree markings can be used together with other elements to experiment more with optics.
Set of 6 lenses 38 mm AM0914 • 6 lenses D 38 mm • double-convex, double-concave, flat-convex, flat- concave, concave-convex, convex-concave • material: glass; till stock last
Set of 6 lenses 50 mm AM0913 • 6 lenses D 50 mm • double-convex, double-concave, flat-convex, flat- concave, concave-convex, convex-concave • material: glass
Wooden lens holder HG0091
Convex lens and concave lens QH0056 Spherical and convex spherical mirror on separate bases. • dia. 10 cm • 2 pcs
Laser refraction tank HG0089
A universal holder for supporting lenses during presentations and experiments in optics. Made of wood, it has a height-adjustable arm with a wing bolt lock. The V-shaped slot will hold lenses from 38 to 50 mm in diameter. • size: 9.7 x 4.5 x 15 cm • till stock last
The model illustrates how a beam of light gets reflected when passing through a different medium (water in an acrylic tank) and how it gets reflected. The transparent tank with water has a scale on its back wall (360°) and a movable arm with a laser activated with a switch • size: disk D 16 cm, H 25 cm; the laser requires a battery
Diffraction grating set HG0127
The set consists of 5 gratings: • with 3 single slits (width 0.05; 0.1; 0.2 mm) • with 3 double slits of 0.05 mm (spacings 0.2; 0.3; 0.45 mm) • with single slits, 2 slits, 3 slits, 4 slits, multiple lines (30 and 60 lines/mm, circular apertures (D 0.36 mm), triangular apertures (side 0.3 mm), square apertures (side 0.2 mm), rectangular apertures (0.6 x 0.28 mm), all slits 0.06 mm wide with spacing 0.05 mm • with 3 rectangular apertures, each formed by lines intersecting at right
A set of optical devices to demonstrate the diffraction and interference of light and to obtain its spectrum. The analysis of the location of light and dark diffraction stripes makes it possible to determine the length of the wave falling onto the grating. They can be mounted on special stands or optical benches. • till stock last
Color mixing apparatus QH0055
A special projector using 3 strong low-voltage LED lamps (red, green and blue) in special holders and sockets to ensure adjustment of the angle of incidence for each colour ray onto the white screen. • size: 22 x 17 x 16 cm • wall fasteners and manual includedl; till stock last
angles, number of lines: 20, 40 and 60 respectively • with round apertures of diameters 0.2; 0.3; 0.4 mm
