Overview
The GL15-K9 Plano-Convex Cylindrical Lens is a precision optical component engineered for beam shaping, line generation, anamorphic imaging, and laser diode collimation in laboratory and industrial optical systems. Fabricated from high-homogeneity Schott BK7 (K9) optical glass—certified to ISO 10110-2 surface quality and refractive index tolerance (nd = 1.5163 ± 0.0005 @ 587.6 nm)—this uncoated lens features a plano surface on one side and a cylindrical convex surface on the other, delivering focused illumination along a single axis while preserving collimation in the orthogonal direction. Its design adheres to classical Gaussian optics principles, with focal length calculated per the cylindrical surface radius of curvature using the lensmaker’s equation adapted for cylindrical geometry. The absence of anti-reflection coating ensures broadband spectral transmission (350–2000 nm), making it suitable for UV-VIS-NIR applications where coating-induced phase shifts or wavelength-dependent reflectance are undesirable.
Key Features
- Optical substrate: High-purity K9 (BK7) glass, certified to ≤0.2% bubble & inclusion content per ASTM F265
- Surface quality: 60-40 scratch-dig per MIL-PRF-13830B, verified via interferometric inspection
- Clear aperture: ≥90% of nominal dimension, with tight edge exclusion zone control (±0.1 mm)
- Centration tolerance: ≤3 arcmin between cylindrical axis and mechanical perimeter, measured via autocollimation
- Dimensional tolerance: ±0.05 mm on width/height; ±0.2 mm on thickness (t), ensuring repeatability in multi-lens mounts
- Thermal stability: Coefficient of thermal expansion (CTE) 7.1 × 10−6/°C, enabling stable performance across −20°C to +70°C ambient ranges
Sample Compatibility & Compliance
The GL15 series supports standard optomechanical integration with SM1 (1.035″-40), RMS (0.8″-36), and custom kinematic mounts. All lenses meet RoHS 2015/863/EU directive requirements for restricted substances and are compatible with cleanroom Class 1000 handling protocols. While uncoated, they comply with ISO 9022-3:2015 environmental testing standards for optical components—including humidity cycling (95% RH, 40°C, 24 h) and thermal shock (−40°C ↔ +85°C, 5 cycles). No regulatory certification (e.g., FDA, CE marking) applies, as this is a passive optical element exempt under EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).
Software & Data Management
As a passive optical component, the GL15 lens does not incorporate embedded electronics, firmware, or data interfaces. However, its geometric and material parameters are fully integrated into industry-standard optical design software libraries—including Zemax OpticStudio (v23+), CODE V (v12.5+), and FRED (v17+). Each lens variant is assigned a unique part number (e.g., GL15-40×20-030, GL15-25-150-VIS) aligned with ISO 10110-12 coding conventions for cylindrical optics. Traceable metrology reports—including radius of curvature (measured via null interferometry), surface flatness (λ/4 PV over plano face), and focal length verification (collimated HeNe beam method per ISO 10110-4)—are available upon request for GMP/GLP-aligned validation workflows.
Applications
- Laser line generation in machine vision inspection systems (e.g., triangulation sensors, structured light projectors)
- Anamorphic beam expansion for diode-pumped solid-state lasers (DPSSL) and fiber-coupled pump sources
- Optical coherence tomography (OCT) reference arm beam conditioning
- Fluorescence microscopy illumination homogenization in widefield and light-sheet platforms
- Educational optics kits for demonstrating astigmatism correction, cylindrical aberration, and focal line formation
- Custom collimator assemblies for LED-based spectroscopic light engines
FAQ
Is this lens suitable for high-power laser applications?
Yes—when operated within ISO 21254-1 damage threshold guidelines for uncoated BK7 (≥5 J/cm² for 10 ns pulses at 1064 nm), provided beam diameter exceeds clear aperture and power density remains below 1 kW/cm² for CW operation.
Can I specify custom radius of curvature or focal length?
Yes—custom R-values and corresponding f-numbers are available under OEM agreement; minimum order quantity (MOQ) applies.
Do you provide mounting adapters or lens cells?
Standard SM1-threaded lens tubes and kinematic mounts are available separately; full mechanical drawings (STEP/IGES) can be supplied for integration into custom optomechanical designs.
What is the typical lead time for bulk orders?
Standard stock sizes ship within 3 business days; custom dimensions require 2–4 weeks depending on dimensional complexity and polishing schedule.
Are measurement certificates included with shipment?
A Certificate of Conformance (CoC) listing nominal specifications is included by default; NIST-traceable calibration reports with interferometric verification are available at additional cost.
