The cheapest spectroscope in the world!
With this easy to build spectroscope you can examine the spectrum of any light source: glowing bodies (sun, incandescent light bulb), fluorescent lamps, etc. On the nano-meter scale you can read the wave length to 5 nm accuracy.
Observe, understand and compare light spectra
A high-precision transmission diffraction grating with 1,000 lines per millimetre makes the spectral colours visible. In this way, the Hand Spectroscope enables the examination of different types of light, from the continuous spectrum of incandescent bodies such as the Sun or a light bulb to the line spectra of fluorescent lamps and many other light sources.

Adult supervision:
Children under the age of 14 should use the kit under adult supervision to avoid risks due to improper handling.
Take care with small parts:
Choking hazard! Keep small parts out of the reach of small children.
Risk of injury:
Take particular care when handling pointed and sharp parts! Use sharp tools with care and take suitable safety measures to avoid injury.
Fire hazard:
Keep away from naked flames and heat sources. Product contains highly flammable materials.
Caution when focussing light: Do not expose lenses to direct sunlight unattended as they can create a focal point.
Danger from sunlight:
Never look directly at the Sun through the spectroscope without using a suitable sun filter, as this can cause serious eye damage.
Adhesive use:
Observe the manufacturer's safety instructions when using adhesives. Work in well-ventilated areas and avoid skin or eye contact.
