What is an optical bench?

Optical bench, also known as an optical rail, is a piece of scientific equipment used in demonstrations including optics and laser light. Like the optical table, the optical bench supports light sources, lenses and mirrors. Optical benches are much smaller than optical tables and their size is a pity to experimental accuracy. Optical benches are not used mainly as a demonstration tool in the classroom. Optical benches are available to buy from many online retailers specializing in scientific equipment.

The use of the optical bench is in many ways similar to the use of an optical table. Each equipment on the rail is held in place with a tightened screw. The screw release allows the user to slip a mirror or light source along the rail. If the screw is completely released, any piece gets from the rail. The ease of assembly allows the user to quickly set the bench.

its design makes an optical bench inappropriate for a reliable scientific experimentu. Small size and cheaper bench materials cause it to be prone to picking up outside vibrations, a variable that could invalidate an experiment using laser light. Also, the bench is just too small to hold the device necessary to carry out the experiment. Thanks to these disadvantages, the optical table is a necessity. Its larger size and more robust materials make it a solid and stable surface that can support multiple mirrors and prisms.

It is not possible to perform extensive experiments, the optical bench is a valuable tool for secondary school teachers or university students who demonstrate the principles of optics. In these situations, the small size and ease of using the optical bench is optimal. After the demonstration, students can use the bench themselves and get a deeper understanding and recognition of optics. Unlike powerful lasers found on most optical tables, Thadice included in the optical benches is low power and for PUsing in the classroom is completely safe.

Many suppliers of scientific devices offer optical benches. The price generally increases for models that are longer and/or include multiple accessories. It is also an option for a teacher to create a set of set by buying only the pieces it needs. If the piece should break during the classroom, most suppliers offer spare parts at a reasonable price. Another advantage is that when spreading, the optical bench occupies a small space in the class.
