Tube Lens (VIS/DUV~NIR)Tube Lens (UV~NIR)
UV(자외), NUV(근자외), NIR(근적외) 대물렌즈에서 나온 평행광을 이미지면에 결상시키는 ‘2nd Objective(Secondary Objective)’ 렌즈 유닛으로, 레이저 가공/가공 모니터링 및 관찰 광학계의 영상 렌즈로 사용됩니다
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.
