Features:
● Continuous variation of magnification 2x ... 8x possible
● Wavelengths 355 nm, 405 nm, 532 nm, 633/780/830 nm or 1064 nm
● Settings of zoom and focussing scales according to product specific graph
● Mounting in customer machine at surface [A]
● Consideration of convergence correction at maximum setting of movable lens elements
● Max. entrance beam-Ø at 1/e2 Gaussian beam (mm) valid for defined zoom factors, beyond the entrance beam-Ø max. = 31 mm / zoom factor. Details can be found in the respective data sheet.
