## Overview

Rainbow Symphony's Linear Diffraction Grating Slides feature 1000 lines per millimeter on durable 2" x 2" slides, delivering bright, clear spectra with minimal visual noise. Perfect for educational use, these US-made slides include a nanometer scale for precise wavelength measurement and are compatible with overhead and 35mm projectors, making them ideal for interactive science demonstrations and classroom experiments.

## Description

Diffraction Grating Slides-Linear 1000 Line/mm. Our 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 visual noise. Our gratings are the principal 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.

## Features

- DIFFRACTION GRATING: Rainbow Symphony's Linear Diffraction Grating Slides (1000 line/millimeter) allow you to directly view and analyze spectra from multiple light sources, including gas tubes, making the study of light and color fun and educational.
- QUALITY MATERIALS: Our 2"X 2" diffraction grating sheet slides were designed with quality material to produce the brightest possible spectrum with a minimal distracting visual noise, while being long lasting. It features efficient embossed holographic elements.
- EDUCATION: Our diffraction grating sheet slides are perfect for classroom or homeschool physics education on visual displays of light diffraction. Each slide has a scale to help you measure wavelength in nanometers, making observations simple to record.
- PROJECTOR COMPATIBLE: These slides can be used to project a spectrum using overhead projectors or a 35mm slide projector for spectrum demonstration purposes. Use in conjunction with colored film gels for additive and subtractive color demonstrations.
- MADE IN THE USA: All of Rainbow Symphony's diffraction grating film slides are made in the US to ensure the quality. These rainbow maker slides are perfect for kids gifts, physics gifts, educational toys, classroom supplies or homeschool supplies.

## Questions & Answers

**Q: Will it chop frozen grapes?**
A: I just tried. This is ineffective against frozen grapes.

**Q: What is the difference between the various options?**
A: Basically the line spacing. We offer 500 ln/mm, 1000 ln/mm and cross axis 13,500 line/ in. The 1000 ln/mm spreads the spectrum the most.

**Q: Your scale is backwards.  Red is the longer wavelength.**
A: I think they meant the scale to be applied to the rainbow colors of the plastic part itself (just as a side reference relating color and wavelength), since the positions of colors on the grating depends on angles etc., they aren't tied to a specific position on the grating anyway.

**Q: Could anybody provide me more technical information or a datasheet? For example, the manufacturing method or the grooves' angle. Thank you in advance**
A: Sorry, just the line spacing.
