Telecentric scanning lens
A characteristic of a telecentric scanning lens is that at least one lens in the lens group has an area larger than the size of the telecentric scanning lens. For example, if there is a 100 * 100mm telecentric scanning lens, there must be at least one lens with a size greater than 100 * 100mm, which means that one of the lenses must have a diameter greater than 100 * 1.414=141.4mm.
Many customers want to buy large format telecentric scanning lenses. For example, some customers told me they want to buy a 300 * 300 format telecentric scanning lens and asked if they have it. I said without this item, even if there were, you wouldn't buy it. Why? Think about it, a 300 * 300 telecentric scanning lens requires one of the lenses to have a diameter greater than 430mm, about half a meter. It's hard to find a polishing machine that can process half a meter of lenses, and a coating machine can't even plate a few pieces at once. It can be seen that this lens is a giant product with complex processing, and coupled with the fact that the telecentric scanning lens is composed of multiple lenses, it can be foreseen that the price of this lens is estimated to be over tens of thousands of yuan per lens. For a down payment of a house in a second tier city to buy a lens, how many customers can afford it?
So in the future, when considering telecentric lenses, those within the range of 100 * 100 may still be available, and larger format lenses are unlikely to be found because they are difficult to find. Even if found, the customers who bought your device cannot afford this money.
In fact, the main purpose for customers who buy this type of lens is to achieve fine lines that meet the standard. If that's the case, I suggest that you use a small negative telecentric basis and then divide the markings to achieve the required precision, which is more feasible. If you can't afford a small format telecentric, then buy a small format f-theta field lens, combined with an XY platform for dividing the table, which can also make the marking lines more precise. But both of these methods have a slight gap in the splicing, as long as the gap cannot be seen by the naked eye.
