It is a device that take a collimated beam of light and

  Shape:Straight Mount without Screw

 Beam expander is composed with two lens of different curvature

 to obtain best effect.

 Master Laser ^TM beam expander has been proved to have

 perfect curvature with small divergence angle and less

 energy loss.

 The role of beam expander is to expand beam spot.

 The laser enter the beam expander where we called

 eyepiece, it is easily broken due to high power.

 The incident lens of beam expander produced by

 Master Laser ^TM is replaceable (we don't suggest

 for other brands).

 The light transmission of the parts increased by

 cylindrical surface polishing, reduction or elimination on

 stray light of the optical system

 Double-side coated anti-reflection coating

 The transmittance of working waveband in co2 laser

 industry reaches 99.9%

 Thin-film coating anti wiping

 Higher luminous flux

 Decrease or eliminate the reflective lights from optical

 lens

 Adopted ZnSe material imported from USA which can

 go with high power density, and increased the light

 transmittance of the parts

 CVD ZnSe imported from America, boasting low

 material absorption rate, excellent high-power

 density endurance, Great scratch resistance.

 Stable focus spot, better effect in cutting and engraving,

 bearable for high power density, and strong thin - film coating

 against peeling off and durable for wiping.

 Customization

 This kind product has many different specifications,

 we provide all the stock size,as following table shows.

 If you can not find the right size you want or you need to buy a non-standard size product,we also provide

 custom made service.

 You just need tell us the parameter and your

 requirement.we will marking the product you need.

 Because the tax rate of some countries are very

 high so we can lower the value when custom
