Laser Lens replacement

[Lance Mills]

Hi everyone, another newbie here, from New Zealand, Very interesting reading up on all the threads. I have a Chinese Laser (surprise surprise) and have managed to crack the lens, in the middle no less. The supplier here seems very reluctant to assist in procuring a new one for me for whatever reason?(after trying for months) so I need to find out where and who to contact regarding a replacement. The machine is from Shanghai Chengen Machinery Co.,Ltd (http://www.diytrade.com/china/manufacturer/161321/main/Shanghai_Chengen_Machinery_Co_Ltd.html), model HS S9060, 80 watt and its performance with the lens as is is substandard as you would guess although it does cut and etch reasonably well concidering.
Its a great source of information on this forum and a comfort to know I'm not alone in this little corner of the world.
Thanks in advance,
Lance

Hi Lance,

Go to www dot aliexpress dot com. No affiliation in any way wit this company.. measure the diameter of your lens. You must be very accurate. for example there are 19.05 mm lenses and 20 mm lenses. As far as focal length goes, if you do not know your lens then the most common Fl is 50.8 mm. This is suitable for most cutting between 0 to 5 mm...... I randomly cose one of the suppliers and pasted below as an example.
