Geometrical Optics; Light Rays and Reflections
Blackboard Optics
What it shows:
With an assortment of plane and curved mirrors, convex and concave lenses, parallel-sided block and prisms, the Klinger 1 Blackboard Optics Kit© allows one to demonstrate all the classic examples in geometric optics by actual ray tracing in...
Fiber Optics
What it shows:
Light is transmitted by a bundle of optical fibers and/or a coiled length of plastic rod, regardless of the twists and turns in the path it must negotiate. Total internal reflection keeps the light confined.
How it works:
A HeNe laser is...
Schlieren Optics
Optical technique that allows us to see small changes in the refractivity of air and other transparent media.
What it Shows
Refraction due to inhomogeneity in air is made visible by our single-mirror schlieren optics setup. The refraction can be caused...

Light and Optics
Optics Disk
What it shows:
All of the concepts summarized by the above keywords can be clearly and quantitatively demonstrated with this piece of apparatus.
How it works:
A light source 1 rotates around the circumference of a large white disk 2 with degree graduations...
Double Refraction
What it shows:
A birefringent substance will split unpolarized light into two polarized rays with different refractive indices and different velocities. A crystal of calcite demonstrates this phenomenon.
How it works:
The optic axis of a crystal is defined...
Edge Diffraction
What it shows:
A point light source will produce seemingly sharp shadows which turn out to be not at all sharp when viewed under magnification. Narrow interference bands are seen within the shadow of a straight edge while more complicated shapes yield...
Optical Analog of Uncertainty Principle
What it shows:
In the Heisenberg uncertainty relation, the momentum of a particle cannot be known with any greater accuracy than h/∆x where h is Planck's constant and ∆x is the uncertainty in spatial position. The more you localize its spatial position...
Sugar Syrups
What it shows:
Certain materials (sugar in this experiment) are optically active because the molecules themselves have a twist in them. When linearly polarized light passes through an optically active material, its direction of polarization is rotated. The...
