X-Cube, dichroic mirrors are amazing!

Published 2023-11-06

An X-Cube is a cube made from 4 prisms with dichroic mirrors that are glued together.

Dichroic mirrors allow some wavelengths of light to be transmitted, some wavelengths are refracted and some wavelengths are reflected.

They can be used to split white light into its constituent wavelengths. So whenever you see two beams of light emigrating from opposite sides of the cube, if you combine those two colours you get white, e.g. cyan and orange, magenta and yellow, red, green and blue.

It can also be used to combine wavelengths from two different sources, e.g. a cyan and orange laser into a white or a red laser and a blue laser into a green laser.

To do this it takes advantage of constructive and destructive interference. (A topic I can make a video on if people request it).

Laser safety:

As for using lasers on an X-Cube (or any reflective surface in general) DO NOT DO IT AT HOME!!!
Misuse of lasers and improper laser safety practices are very common when handling such equipment and it’s not uncommon to receive temporary or often permanent damage to your eyes.

If you do wish to own a laser make sure you buy it from a credible source and read up on the class rating system. If the seller is not credible I highly recommend you invest in a pair of laser safety glasses from a credible source. Make sure the colour of the glasses is opposite to that of the colour of the laser you wish to own.

*Don’t compare it on a standard colour sheet, search up a chromaticity diagram and hold a ruler or straight object from the wavelength of your laser, through the centre of the white of the diagram, and the opposite wavelength to your laser is the desired colour of the glasses.

I recommend researching about lasers from a certified laser glasses or testing company. High OD wrap around goggles are the best but they’re super expensive.

I don’t own proper goggles but I was shielded during the entire video and my laser isn’t particularly powerful as far as they go. Although it’s actually easier and cheaper for sellers to make powerful infrared lasers that to make weak coloured lasers, this one is a typical IR laser with a crystal that changes the output wavelength to green, however being a cheap laser with the sellers not caring about safety the mirrors are poorly fitted and the IR filter is faulty if there’s one at all, so the true power could be far higher and I wouldn’t even know without an IR camera. So be careful, a laser could seem weak but could actually be putting out monstrous amounts of IR radiation that would blind you instantly if you even looked at the spot on a wall!

You’ve been warned!

The different colors are just amazing..

😊Thank you, Oscar. Wow, that is a great video. I can't lie,I pretty much enjoy all your content on your videos.🤔 I wonder what my next surprise is gonna be...
