Infrared (NIR) Objective Lens / PAL-100-NIR-LC07
This is a high NA infinity corrected objective lens for laser processing (fundamental of 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.
◦It is also used for the observation of Near Infrared light.
◦High resolution type (NA=0.65) is also available.
◦This objective lens can be used with a pulse laser of visible light (532nm).
◦Laser Damage Threshold(reference): 0.1J/cm2 (532nm), 0.2 J/cm2 (1064nm) (Laser pulse width: 10ns, repetition frequency: 20Hz)

Guide | ▶Available fixed objective lens holder (LHO-26). WEB Reference Catalog Code/W4024 ▶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) and for laser unit with coaxial illumination and observation (OUCI-2). WEB Reference Catalog Code/W2041 |
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, designed specifications may not be achieved due to aberration. ▶If the incident laser beam femtosecond is below 100fs |
