Sauna Revival is a Minnesota based sauna web store specializing in high-end Finnish sauna heaters, lighting solutions, and other sauna products.

With a fiber optical heater lens, you can illuminate your sauna heater for that added oomph to your sauna lighting. See the steam rise from your sauna heater as you enjoy the löyly.

A suspension of particles will show you which path the beam is traveling. Along the thin line where the beam is shining, you can see how the particles are moving in the solution. This is called the laser sheet method.

With this Cariitti accessory* a LED fiber light is bought over your sauna heater (to be installed in the ceiling above the heater) to illuminate it with a glass fibre. A lens is installed on the back end of the fibre.

Be very careful in a dark room—prepare everything you’ll need in advance; clear the path from the light switch to the table or ask someone to turn the lights off.

Kids are now able to engage with science in a way that they simply wouldn’t have been able to in the past as they shrink themselves down to see the world at a molecular level

The beam can pass not only through the air, but also through transparent objects. The light spot on the wall will show how passing through the cylinder changes the path of the beam.

You won't see the beam moving through the air, but you can see the light spot where the beam stops. Remember the shape the light spot makes when there is no obstacle in front of the laser.

Fast fact! Here, you used a laser—a device that shines a narrow beam of light rays  in one direction.Turns out that transparent objects not only transmit light, but also change its direction. Light rays bend when they pass from one medium (air) to another (glass, water). This phenomenon is called refraction.

Due to refraction, the light spot  turns into a line when you place the transparent cylinder  in the path of the beam . Let’s talk about how this happens! Before encountering the cylinder , all the rays  are going in one direction. Then they bend twice: when they enter the cylinder, and when they exit it. In total, the rays are refracted in a way that makes them gather together behind the cylinder and then diverge to the sides , spreading like the feathers on a hand fan.

To make the path of the ray visible, you need to put many small, reflective obstacles in its path—such as a glitter suspension.

To observe how a light beam moves through the air, you’ll need something more sophisticated than a regular light source. A laser will provide a narrow beam of light.

To visualize the light’s path, one can use a suspension containing tiny reflective particles . As they pass through it, the rays are reflected by the particles that they meet along the way. The reflected rays reach our eyes, which is how we see the path of the beam. From the side, it seems that the laser is cutting the glass of liquid like a knife.
