Boosting your industry’s optical precision capabilities relies on leveraging the latest technological advancements. Great precision, standardized products, and versatile components set you apart in a competitive industry.  

Optical flats and windows are two such optical components that can be used for various applications. Using these products, you can measure, analyze, and perfect the other optical components.

Optical Flats

These fused silica optical flats can either be single-sided or double-sided and can be used in several applications. Some of the ways optical flats you can utilize are in testing the precision and wear in gauge blocks, as flat optical windows to meet interferometry requirements, and testing optical components in other precision optics.

This optical grade glass is precisely polished and lapped to be extremely flat on one of both sides. With a flatness of either λ/10 or λ/20 and made with either high-quality fused silica or BK7, optical flats are used to compare the flatness of other surfaces.

Using optical flats as a point of reference, the surface of other optical components is tested. The process involves placing the polished surface in contact with the surface that’s being tested; light and dark bands will result from the use of monochromatic light.

The resulting bands indicate the flatness of the surface being tested and provide a visual representation of the interference fringes and the spaces and curves between them.

Optical flats range from 25mm to 200mm and have a flatness of about λ/10 or λ/20. The lower cost BK7 offers a relatively lower quality but it’s ideal for applications that are less demanding.

Optical Windows

Made with materials of varying grades, optical windows are often produced with BK7 grade A, UV Fused Silica, and Sapphire. Among their various applications, experts in the astronomy, aerospace, medical physics, military, and biomedical industries use optical windows.

These transparent optical products allow light to pass into an instrument. The wide variety of optical windows—square, circular, and rectangular—are comprised of two flat, precisely polished surfaces. The optically transparent and flat surfaces are used to protect electronic sensors and optical systems from environmental elements.

Optical windows are specifically designed with the intent to minimize absorption and reflection while promoting transmission.

High-quality optical windows, which separate two environments while letting light pass through, are ideal for use in various industrial applications. Depending on your requirements, you should select an optical window that’s made with the ideal material, resistance, wavelength range, and transmission.

Lens Design 

Lens design products and services can enrich your life in many ways. To ensure that you're obtaining the best goods available to you, it's important that you locate a product and service supplier that is known for operating in excellence and expedience. Find the perfect lens design retailer by ensuring that the company conforms to all of the following traits: 1. Positive Online Reviews. When you start looking for a lens design product and service retailer, it's important to pay attention to what other people are saying about the company. Companies that consistently attain positive online reviews from former and current customers typically do so because they regularly offer excellent products and stellar services. If you come across a lens design company that has an abundance of negative reviews, keep it moving. 2. Warranties. When it's time for you to find the ideal lens design company, warranties are something you should definitely look into. This is the case for several reasons, including that warranties are the feature which enable you to attain repair services on a lens design product that fails to function correctly. For this reason, it's a good idea to ask a customer service representative whether the lens design products come with warranties. 3. Reasonable Rates. No one wants to break the bank to get the great lens design products they want, and they shouldn't have to. You can avoid this move by doing some research to determine what the average rates are for Lens design products. After you've done some cross comparisons, you can pick the most cost-effective brand available. Conclusion If you're ready to attain excellent lens design products, you need to first find the ideal retailer. You can make it happen by seeking out a retailer that has positive online reviews, warranties, and reasonable rates.

Are you looking for a company to design lenses for you? Have you looked at American companies and already realized how expensive they can be? If so, you may want to follow the lead of other companies that also lens design, and look for a Chinese company to offer it to you.

Here are the steps you will need to follow to get just that. Find a company online that offers free estimates -- Your first step is to find a company that can give you a quote for any lenses you will be buying or having designed. Contact the company -- Complete the form requesting an estimate with as much detail as you possibly can. The manufacturer will still likely contact you with additional questions, but it will make it even easier if you have already provided some of the information regarding your order up front. Go over the estimate -- Once you have submitted all the information necessary, you should receive an estimate or estimates with one to two days. At this point, spend time going over each estimate so you are sure everything has been covered. Take special care to notice the price per unit if you decide to order larger quantities as, especially from China, this really can bring down the price. Place your design order -- Once you are happy with the company and the price, place your order. Do be sure to ask how long a typical Lens design order takes, and when you can expect yours to be completed. Delivery time -- Finally, make sure you ask about average delivery times so you can make arrangements for a faster way to receive your order if needs be. In most cases, though, you should receive it in just a couple of weeks.
