Why is the price of 355nm laser so expensive

There are several reasons why 355nm lasers are relatively expensive

First, manufacturing 355nm lasers requires the use of special materials and processes, which increases production costs.

Second, the shorter wavelength of 355nm lasers requires higher energy density and higher power to achieve the same effect, which also increases manufacturing costs.

In addition, the market demand for 355nm lasers is relatively small, and the production scale is small, which also leads to a rise in price to a certain extent. Generally speaking, the high price of 355nm lasers is mainly due to the factors of manufacturing cost and market demand.
