PFL-10-UV/NUV-AG Lens

AS ONE

[Features]
· An objective lens that can be used with YAG pulsed laser processing equipment with second (532 nm), third (355 nm), or fourth (266 nm) harmonic waves.
· Featuring a YAG third harmonic that achieves high transmittance.
· With a large working distance (WD), natural observational images can be obtained right up to the periphery of the visual field by compensating for the curvature of the field.
· An objective lens used for coaxial observation systems, optical systems using lasers, etc., using infinity compensation.
· Samples can be observed in visible light (400-500 nm).
· A fixing type objective lens holder (LHO-26) is available.
· An observation unit with coaxial illumination (OUCI-2) and dichroic mount for laser introduction (DIMC) are available as lens barrels for laser processing.
· * Widen the incident beam to half the pupil diameter if using the objective lens for laser processing.
· * A small condensed light spot cannot be achieved if the incident beam is thin.
· * Also, excessive laser energy concentration may damage the objective lens.
· * If using the objective lens for laser processing, there is a chance that the objective lens front surface may become dirty due to spray from the processing work.
· * Use after ensuring sufficient working distance (WD) or inserting thin protective glass to protect the objective lens from dirt.
· * The magnification is the value taken when using the imaging lens f = 200 mm.
· * The magnification may differ if used with microscope lens barrels from other manufacturers.
· * Calculate the actual magnification by checking the focal distance of the imaging lens of the lens-barrel to be used and the ratio between the focal distance of the imaging lens and that of the objective lens.
