Overview
The MiXran Meg1010 double-convex (DCX) lens is a precision optical component engineered for collimation, focusing, and imaging applications across visible (VIS), near-infrared (NIR), and short-wave infrared (SWIR) spectral bands. Fabricated from high-homogeneity N-BK7 borosilicate crown glass, the Meg1010 series adheres to ISO 10110-1 and ISO 10110-3 standards for surface form, surface quality, and material specifications. Its symmetric geometry—where both surfaces possess identical radius of curvature (R₁ = R₂)—ensures minimal spherical aberration for on-axis point sources and simplifies alignment in relay systems, beam expanders, and laser cavity optics. The lens operates on the fundamental principle of paraxial refraction governed by the lensmaker’s equation, delivering predictable focal behavior with high wavefront fidelity under standard illumination conditions.
Key Features
- Precision-ground and polished N-BK7 substrates with surface flatness ≤ λ/4 @ 632.8 nm per surface
- Standard surface quality of 40–20 scratch-dig per MIL-PRF-13830B
- Centration tolerance ≤ 3 arcminutes, enabling integration into high-stability optomechanical assemblies
- Clear aperture ≥ 90% of nominal diameter, supporting uniform illumination and reduced vignetting
- Multiple anti-reflection coating options: uncoated, VIS broadband (400–700 nm, Rₐᵥg < 0.5%), NIR broadband (650–1050 nm, Rₐᵥg < 0.8%), and SWIR broadband (1000–1650 nm, Rₐᵥg < 1.0%)
- Consistent edge thickness control (Te) and center thickness (Tc) tolerances of ±0.05 mm for reproducible mounting and thermal stability
- Compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006
Sample Compatibility & Compliance
The Meg1010 lens family supports integration with industry-standard lens mounts—including SM-threaded (e.g., SM05, SM1, SM2), retaining rings (e.g., RMS, LM-series), and kinematic cell adapters—enabling compatibility with Thorlabs, Newport, and Edmund Optics mechanical platforms. All coated variants undergo environmental durability testing per ISO 9211-3:2019 (adhesion, humidity, abrasion) and demonstrate no measurable degradation after 24 h at 85 °C / 85% RH. Uncoated lenses are suitable for UV-VIS applications where custom coating or vacuum deposition is required. The product line conforms to general laboratory equipment safety requirements outlined in IEC 61010-1:2010 and is designated as Class 1 optical component per EN 60825-1:2014.
Software & Data Management
While the Meg1010 is a passive optical element and does not incorporate embedded firmware or digital interfaces, its full parametric dataset—including exact EFL, BFL, R₁/R₂, Tc, Te, and coating spectral reflectance curves—is provided in standardized Zemax .zmx and CODE V .seq import formats upon request. Each lens batch is assigned a unique traceable product number (e.g., GL12-025-025-VIS) linked to QC documentation including interferometric surface map reports, spectral transmittance measurements (PerkinElmer Lambda 1050+), and dimensional inspection records (Mitutoyo Coordinate Measuring Machine). These records are archived for 10 years and available for GLP-compliant audit trails upon formal request.
Applications
- Laser beam shaping and collimation in DPSS, diode, and fiber-coupled systems
- Objective and relay lens elements in VIS/NIR spectroscopy instrumentation (e.g., FTIR, Raman, OCT)
- Imaging optics in machine vision, metrology, and industrial inspection systems operating within 400–1650 nm
- Optical test benches for MTF measurement, wavefront analysis, and PSF characterization
- Custom-designed achromatic doublets when paired with complementary concave or plano-concave elements
- Education and research laboratories requiring cost-effective, specification-transparent optical components
FAQ
What is the refractive index of the Meg1010 lens at 587.6 nm?
The N-BK7 substrate has a nominal refractive index of nd = 1.5168 at the helium d-line (587.6 nm), per Schott N-BK7 datasheet revision 2023.
Can the Meg1010 be used in high-power laser applications?
Uncoated and VIS-coated versions are rated for continuous-wave (CW) power densities up to 500 W/cm² at 532 nm; NIR- and SWIR-coated variants support up to 1 kW/cm² at 1064 nm and 1550 nm respectively, assuming proper heat sinking and clean beam profiles.
Is there a certificate of conformance included with each shipment?
Yes—each order includes a manufacturer-signed Certificate of Conformance (CoC) listing measured EFL, surface quality, coating performance, and compliance with ISO 10110 and RoHS.
Are custom diameters or focal lengths available?
Standard configurations cover diameters from 2 mm to 100 mm and EFLs from 1.36 mm to 100 mm; non-standard geometries are available via OEM agreement with minimum order quantities and extended lead times.
How should the lens be cleaned to preserve coating integrity?
Use solvent-grade acetone or isopropanol with Class 100 cleanroom-grade lens tissue; avoid ultrasonic cleaning unless explicitly approved for the specific coating variant.
