SL15
PURPOSE
This ISO 12233 test chart, based on the 1995 version, is designed to evaluate the resolution performance of monochrome and colour digital cameras. It enables both manufacturers and users to determine the point at which fine image details are no longer accurately reproduced by a given imaging system. In addition to general resolution testing, this chart is suitable for laboratory-based performance benchmarking and can be used to characterise the frequency response and optical performance of a complete system—camera, lens, and display device. It is widely applicable across industrial inspection, broadcast equipment evaluation, machine vision, and product development.
Both the chart size and the active image area measure 200mm × 152mm (approx. 8" × 6").
MATERIAL
- Soda Lime Glass: Optical-quality soda lime glass with an etched chrome pattern. Designed to be viewed right-reading through the glass side, onto the rear chrome surface.
PATTERN DESCRIPTION
- Central double-frequency concentric circles for focus calibration.
- 100–600 LP and 500–2000 LP resolution wedges for measuring optical resolution in horizontal, vertical, and corner regions.
- 100–1000 LP square wave sweeps to evaluate limiting resolution in both axes.
- 5° slanted-edge bars and squares for spatial frequency response (SFR) measurements.
- Multi-angle slanted-edge “star pattern” to extend SFR characterisation.
- 100–1000 LP short black lines for evaluating pulse response in horizontal and vertical directions.

INSPECTION
All photomasks undergo a comprehensive inspection process. Key parameters such as Critical Dimension (CD) and feature uniformity are measured and recorded. High-magnification images (Nikon MM40 at 900×, OGP ZIP 300 at 400×) are stored with production data. For sectors requiring compliance documentation—such as medical or automotive—optional inspection certificates can be included with the order.
Standard: Full inspection performed; no documentation supplied.
Certificate of Conformance: Confirms compliance with internal inspection standards.
Certificate of Measurement: Up to 10 line/space dimensions (width and pitch) can be measured and documented. CAD or marked drawing may be required. Additional measurements available on request.
AVAILABILITY
Standard production turnaround is 5 days from order receipt. Please allow additional time for larger or made-to-order glass plates.

| FAQ | FREQUENTLY ASKED QUESTIONS Q: The standard pattern doesn’t match my requirements. Can a custom version be produced? A: Yes. While the patterns shown are standard configurations, we can produce custom designs based on your specifications. Please note that pricing and lead times will vary depending on complexity and volume. Q: What is the typical lead time from order to dispatch? A: We aim to keep these products in stock for immediate dispatch. However, please allow up to 5 working days depending on order volume and current production workload. For urgent requirements, contact us directly to check availability. Q: Can you provide a high-resolution image or scaled preview of the pattern? A: Yes. High-resolution graphic previews can be emailed upon request. Please contact us via Live Support or email to receive sample files. Q: Are other materials available for this product? A: Yes. Standard versions are produced using low-reflective chrome on soda lime glass, but we can supply alternatives including quartz, Borofloat®, or other substrates. Masking layers such as aluminium, gold, or ITO can also be specified. Minimum order quantities apply for non-standard materials. Q: Can the glass be supplied in different thicknesses? A: Yes, alternate glass thicknesses can be supplied on request, subject to material availability and minimum order quantities. Q: Can I specify exact tolerances or reference dimensions for inspection? A: Yes. For customers requiring dimensional validation, we offer Certificate of Measurement services. You will need to supply a CAD file or annotated drawing identifying the features to be measured. Q: Are these slides reusable or suitable for cleaning? A: The chrome patterns are durable and can be cleaned with appropriate optical cleaning agents. Avoid abrasive materials. Reuse is possible depending on your application and handling practices. Q: Is there a minimum order quantity? A: There is no minimum order for standard stock items. For custom designs or non-standard materials, minimum order quantities will apply. |
