Spherical Lenses
According to the shape and function, spherical lenses can be divided into plano convex lenses, plano concave lenses, biconvex lenses, biconvex lenses, meniscus lenses, plano convex cylindrical lenses, circular cylindrical lenses, aspheric lenses, achromatic lenses, double glued lenses, triple glued lenses, etc. The lens has the functions of converging line, diverging light and beam shaping in the optical path, and the plano convex lens/ biconvex lens converges the light; Plano concave lens/ double concave lens will diverge light; Achromatic lens can correct chromatic aberration.
Borisun Optics can provide Ultra-precision lenses made of optical glass materials (such as K9, BK7, B270, etc.) for applications in the visible spectrum band, and lenses made of optical crystal materials (such as Zinc selenide, Zinc sulfide, Calcium fluoride, fused silica, etc.) for applications in the near-infrared/infrared/ultraviolet spectrum band. Lens products are widely used in optical imaging, laser detection, Optical communication, life science, optical lighting and other related fields. Borisun Optics is a manufacturer has a large inventory of standard lenses that can be supplied from stock or customized according to your application needs.
Higher Precision, Accurate Imaging
High Cleanliness
Borisun has redefined precision optical processing and improved the surface accuracy to PV≤1/20λ, far exceeding the average level of PV≤1/10λ to PV≤1/5λ.
Surface Roughness
While others regard 0.5nm as a higher standard, Borisun has reached a higher surface roughness standard of Ra≤0.2nm, leading the field of precision optics.
High Surface Accuracy
In terms of RMS, Borisun has elevated itself to a new level of precision optical manufacturing with its outstanding 1/150th of a second compared to the typical standard of 1/50th of a second.
