These Holographic Diffraction Gratings are highly efficient embossed Holographic Optical Elements (H.O.E.). Diffraction Gratings are used for the direct viewing and analysis of spectra from different gas tubes and other light sources. The quality of the spectrum produced from our gratings is the brightest possible with a minimum of distracting lente noise. Our gratings are the elemental component in a spectroscope and are used for experiments pertaining to the study of light and color. Project a spectrum using an overhead projector or 35mm slide projector for spectrum demonstration purposes. Use in conjunction with colored film gels for additive and subtractive color demonstrations.

To receive the Best Value discount:
Add all products described in the promotion to your Shopping Cart in one of two ways:
Via the “Add both to Cart” button in the promotion description, OR
Via the “Add to Shopping Cart” button on each respective product information page.
The amount of the Best Value discount will be reflected on the final order checkout page and will be allocated proportionally to all promotion items in the Shopping Cart, including the Best Value item itself. For example, if the promotion offers $5 off one item worth $10 when you purchase two qualifying items worth $20 each, the $5 will be divided proportionately between the three items, so that the Best Value item will appear with a $1 discount, and each of the two other qualifying items will appear with a $2 discount.
