2nd Objective Lens Units

Used to focus parallel light beams coming through CFI60-2 / CFI60 Objectives and CF&IC Objectives onto the image plane.

Built-in Type 2nd Objective Lens Unit

• Compatible with CFI60-2, CFI60 and CF&IC infinity objectives.

• Focal length: f/200mm.

• To obtain the optimal objective performance, keep the distance between the lens unit and the objective's shoulder within 100-200mm as shown 

  in the diagram at right.

TV-Use 2nd Objective Lens Unit 0.5×/ TV Relay Unit 1×

• Image plane magnification: 0.5×; Focal length: f/100mm.

• Image plane magnification: 1×; Focal length: f/200mm.

• With a field number of 11mm, this lens unit can be used with CCD cameras smaller than 2/3-inch types.

• Distance between the lens unit and the objective's shoulder: 60-160mm (110mm optimum).

• Compatible with Universal Epi-Illuminators (LV-UEPI-N, LV-UEPI2, LV-UEPI2A, and LV-EPILED).

CFI Tube Lens Unit

This unit is attached to infinity objectives when neither a binocular or trinocular eyepiece tube is used.

• Infinity Tube Lens Unit for CFI objectives (chromatic aberration-free infinity corrected objectives).

• Focal length: 200mm (7.87 in.)

• To obtain the optimal objective performance, keep the distance between the tube lens and the objective’s shoulder 

  within 70–170 mm (2.76–6.69 in.).

Ultraviolet secondary objective (lens for laser)

• Secondary objective lens for use with ultraviolet objective lens UV, near-ultraviolet objective lens NUV, and near-infrared objective lens NIR.*

• Use in laser machining systems and as imaging lenses for visible wavelength observation optics.
