    Взял взамен штатной оптики на свой лазерный гравер 2500 мВт. Фокусирует немного лучше, но неудобно крутить, из-за малых размеров. И, так же как и штатную оптику, приходится подматывать фум-лентой, чтоб убрать болтанку по резьбе, обеспечить плавный ход и некоторую фиксацию после

    This lens significantly improved my 7000mW fixed focus Laser. After removing the original lens which has some silicone on the thread in order to make it fixed I found out that at other focal points of the original lens that the spot became pretty wide the further away the worse it got. After I replaced the original lens(only one single lens in it) with the lens system the ray became for more tighter and and smaller, so it improved the overall performance significantly. No it is able to cut through

    Installed to my 1W laser modules and it increased the intensity of the beam. I can now reduce the output power to avoid over burns and hopefully this increases the lifespan of my laser modules. Highly recommended if you own a DIY laser engraver.
