Near Ultra-violet (NUV) Objective Lens / PAL-10-NUV-LC11
This objective lens can be used for laser machining using pulsed laser of THG (355nm) YAG laser. Its glass-thickness- compensation optical design makes it possible to realize an ideal beam spot size and quality even if it was processed thorough a cover glass.

◦Two kinds objective lenses are available. They are designed to correct aberration depending on the thickness of cover glass. (t= 0.7 mm and 1.1 mm)
◦With its long working infinity correction function; this objective lens can be used for a laser system and coaxial observation.
◦This objective lens can be used with a pulse laser of visible light (532nm).
◦Laser Damage Threshold(reference): 0.05 J/cm2 (355nm), 0.1J/cm2 (532nm) (Laser pulse width: 10ns, repetition frequency: 20Hz)

Guide | ▶Available fixed objective lens holder (LHO-26). ▶When the objective lens is fixed to a 2 axis holder, please consult our Sales Division. ▶For laser processing, we offer a dichroic block (DIMC-355R) and for laser unit with coaxial illumination and observation (OUCI). |
Attention | ▶When an objective lens is used in laser processing, use the diameter of the incident beam to extend to a size of half the pupil diameter (1/e2). A small light spot cannot be achieved when the incident beam is too narrow. Please note if there is a laser energy density increase, there will be a high possibility of damage to the objective lens. ▶When the thickness of cover glass is not same as the specified |
