    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 фокусировки.

    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 black foam way less conical than it ha done bevore. However - almost al laser of this kind exhibit a line like focal "point" so, in order to perfectly make it a real focal point it would need an astigmatic lens system!
