What is a First Surface Mirror, and how does it differ from a standard mirror?
Standard mirrors (rear surface mirrors) have reflective coatings behind the glass, forcing light through glass media and causing secondary refraction ("ghosting"). A First Surface Mirror has its reflective coating on the front surface, allowing light to reflect directly without traveling through glass, delivering precise, distortion-free optical imaging.
Are you a direct First Surface Mirror manufacturer in China? Where is your factory located?
Yes, North One Glass Technology Co., Ltd. is a professional Chinese factory and source supplier specializing in deep glass processing and optical coatings, operating large-scale vacuum magnetron sputtering lines in China.
What is the visible light reflectance of your First Surface Mirror glass?
Our standard first surface mirror achieves a visible light reflectance of up to 95%, delivering higher reflection brightness and lower light energy loss than standard commercial mirrors.
Does the mirror coating cause color shift? How is your product's color performance?
Many market mirrors exhibit greenish or yellowish color shifts upon reflection. North One Glass optimizes sputtering parameters so that the surface color LAB values are close to a neutral colorless tone, accurately reproducing true light colors.
What glass thickness options are available for First Surface Mirrors?
We provide a comprehensive range of thicknesses: 1.1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, and 15mm, meeting diverse structural requirements from lightweight instruments to heavy industrial machinery.
What standard sizes do you offer, and can you customize special dimensions?
Our standard sheet sizes include 915x1220mm, 1830x2440mm, 2440x3660mm, 3300x4880mm, and more. We also offer custom jumbo sizes up to 3300x16000mm, along with precision cutting, edging, and drilling according to client drawings.
What is the wholesale price of First Surface Mirror glass?
Purchasing price depends on thickness, size, quantity, and custom fabrication requirements. As a direct source factory, North One Glass offers highly competitive factory-direct wholesale pricing. Contact our sales team for an exact tiered quote.
How does choosing North One Glass size specifications save procurement costs?
We maintain an extensive array of standard raw sheet dimensions. B2B buyers can select raw sizes optimized for their target component dimensions, significantly improving sheet yield, reducing edge scrap waste, and lowering unit purchasing costs.
Is the coating layer of the First Surface Mirror susceptible to scratching or peeling?
While traditional front coatings can be fragile, North One Glass utilizes advanced vacuum magnetron sputtered hard-film technology. The coating layer exhibits superior adhesion, oxidation resistance, and scratch resistance under normal industrial handling and proper maintenance.
Why should projector manufacturers prioritize First Surface Mirrors?
High-definition 4K and laser projectors demand maximum light throughput and crisp imaging. First surface mirrors eliminate ghosting caused by secondary reflections while preserving maximum lumens, significantly enhancing projection brightness and contrast ratio.
What quality control tests do your products undergo before shipment?
Every batch undergoes rigorous quality testing: spectrophotometer measurement for visible light reflectance and LAB color values, thickness and coating uniformity inspection, and cross-hatch tape adhesion tests to ensure film firmness.
How do you prevent glass breakage during international long-distance transit?
We utilize industrial-grade packaging solutions. All sheets are packed in sturdy fumigation-free wooden crates, separated by anti-mold paper or moisture-proof powder, and padded with high-density shock-absorbing foam, resulting in extremely low transit damage rates.
How should First Surface Mirror glass be properly cleaned and maintained?
Since the optical film is on the outer surface, wipe gently using a clean microfiber cloth or sterile cotton swab dampened with isopropyl alcohol (IPA) or deionized water in a single direction from center to edge. Avoid abrasive materials or strong acid/alkaline cleaners.
Do you have a Minimum Order Quantity (MOQ)? Are sample orders supported?
To support R&D testing and trial orders, we support small sample orders for standard thickness sheets. For mass custom orders, reasonable MOQs are set based on production schedules. Please contact us for details.
What is the typical lead time from order placement to shipment?
Standard stock sheets can be dispatched rapidly. Custom orders requiring special cutting, drilling, or jumbo sizing typically ship within 7 to 15 working days following deposit confirmation and drawing approval.
