(1) Un-mounted Single-element Scan Lenses, STSL Serieshttp://www.sintecoptronics.com/scanlens2.jpg
STSL scanner lenses specially designed and optimized for use in CO2 laser 2-axis galvo-scanner systems with full beam diameters of up to 15.0mm. Mirror sets appropriate for use with beam diameters up to 15mm require an increase in mirror separation in comparison with smaller mirrors. These changed optical conditions are catered-for by the STSL series. These single-element lenses are designed to represent the best achievable compromise for on-axis and off-axis aberrations, field flatness and F-theta characteristics, obtainable using single-element spherical-surface designs of (standard) 48mm diameter and 3mm edge thickness. The lens material is ZnSe.

Remark:
(1) The lenses are meniscus form; one concave and one convex surface.
(2) The concave always faces the incident beam.
(3) For all STSL lenses, the diameter is 48.0 +0/-0.1 mm, and the edge thickness is 3.0 +/-0.1 mm.
(4) X scanning mirror is 34.8mm from the edge of the first (concave) surface and the Y scanning mirror is 17.1mm from the edge of the first (concave) surface.
(5) Default is un-mounted. Mounted version is available upon request. Following is the pictures of the mount:

(3) Mounted 2-element Scan Lenses, STC Series
The mounted 2-element scan lenses are 2-element designs for CO2 laser beams up to 15mm diameter, supplied complete in a mechanical housing. These lenses give excellent F-theta performance, with resolution (focused spot size) at, or very close to the diffraction limit over a flat image plane. Variation of spot size (standard deviation from average spot size over the full scanned field) is minimal.The lens material is GaAs.

هل هذا ما قصد ارجو ان يكون هو والا ففصلي ماذا تريدين
اشكرك اخي اكريم علي مساعدتي ولكن للاسف ليس هذا ما قصدته
ولكني اريد شرح مفصل للموضوع وما هي اهميته في التطبيقات العملية والاهم من ذلك كله شرح الفكرة الفيزيائية
ولا يهمني كثيرا الجهاز المستخدم ولكن يكفي رسم بسيط لتوضيح القوانين المستخدمة في كلا الموضوعين

طيب بما يخص التطبيقات العلمية فهي امامك
اما الشرح الفيزيائي
فامهليني قليلاً
