Holographic Diffraction Film

Ideal Choice for Spectroscopy Experiments
Holographic diffraction grating film is used to break up white light into all the colors of the spectrum. It is an ideal choice for spectroscopy experiments, since holographic gratings exhibit significantly sharper diffraction orders than their ruled counterparts by reducing the amount of stray light produced. This results in an increased ability to view absorption and emission lines. Each grating is 6" x 12".

Combined shipping is available only if you contact us before making additional purchases. Many items can be shipped at substantially lower cost (some are even free). Please do not ask for reductions after ordering.



SHIPPING AND HANDLING COST INCLUDE ALL OF THE FOLLOWING COST;

  • POSTAGE OR TRANSPORT CHARGES
  • SHIPPING INSURANCE
  • CUSTOMER SERVICE FOR LOST AND DAMAGED SHIPMENTS
  • PACKAGING TIME AND MATERIALS
  • DELIVERY TO SHIPPER
  • AUCTION FEES
  • PAYPAL, CC OR GOOGLE CHECKOUT FEES


SOME TIME AGO, THE NUMBER AND VARIETY OF THE ITEMS WE SELL BECAME TOO LARGE TO DETERMINE SHIPPING COST FOR. THE TIME REQUIRED TO RESEARCH SHIPPING COST AND THE DIFFICULTY IN GETTING THE INFORMATION TO THE BUYER EXCEEDED ALL OTHER LABOR COST COMBINED. TO RESOLVE THIS DIFFICULTY, WE CREATED A DATA BASE WHICH ACCUMULATED THE SHIPPING COST FOR EACH ITEM, DIVIDED THOSE COST BY THE NUMBER OF ITEMS SOLD AND CREATED A FIXED COST FOR SHIPPING AND HANDLING AS AN AVERAGE COST. THIS MEANS THAT SOME BUYERS WILL PAY MORE THAN THE ACTUAL COST OF SHIPPING AND HANDLING AND OTHERS WILL PAY LESS, BUT THE COST ARE LESS FOR EVERYBODY BECAUSE YOUR ORDER REQUIRES MUCH LESS TIME TO SHIP.

Google checkout fees are lower than paypal, so we discount the cost including shipping and handling 5% if you pay with Googgle checkout. Just let us know and we'll send an invoice. You can use any credit card through Google checkout.
