1. The importance of infrared lenses The lens is an indispensable part of the thermal imaging camera. Its function is to focus the infrared radiation of the target on the infrared detector, and after photoelectric conversion and image processing, a good contrast image is finally formed. The quality of the infrared lens largely determines the performance of the infrared camera. 2. Factors to Consider When Choosing an IR Lens 1. Band Infrared lenses  should be specially designed according to their operating band to optimize their performance. The infrared materials used in infrared lenses of different wavelengths are also different. 2. Vignetting Generally speaking, IR lenses do not allow vignetting. For the lens used in the infrared cooling detector, if the lens has vignetting, it cannot meet the 100% cold aperture efficiency design principle, and the stray radiation will affect the performance of the infrared thermal imager. 3. Focal length and field of view Infrared lenses are usu...

With the growing popularity of powdered baby food, spices and beverages, the demand for powdered packaging or packaging machines is also on the rise. New powder packaging businesses are also emerging to keep up with the trend. Having a good understanding of the basic aspects of packaging can ensure the success of your business.   What is a Powder Filling Machine? A  powder filling machine  is used in the effective filling of a wide range of powder products may they be free-flowing or non-free-flowing. Cohesive powders, such as table salt, are called free-flowing and will not compress and maintain their shape even when you apply pressure to them. Meanwhile, you can compress non-free-flowing powders, like milk powders, because they are non-cohesive and they will retain their shape when you manipulate their particles. Powder filler machines come in different automation levels and machine designs. The type of machine you will need will depend on whether you want to ...

  Hot-dip galvanization  has been extensively used to prevent corrosion for 100 years. Hot-dip galvanized steel has a great lifespan. This effective form of galvanization provides 2 levels of protection : – Barrier protection – Cathodic protection   In Cathodic protection, Zinc protects the underlying material. If any part is scratched, Zinc will prolong its protection. Zinc can also function as a barrier slowing down the corrosion rate.   What is Hot Dip Galvanizing? Hot dip galvanizing is a process developed to prevent steel from corroding. Before the process can take place, the steel goes through a thorough chemical clean which removes all rust, oil and mill scale from the surface. When the cleaning solution has been rinsed off, the coating process can begin. The steel is dipped into a bath of molten zinc heated to around 450°C (860°F) before being left to cool in a quench tank. When the cooling process is complete, the zinc coating is then metallurgically bonded ...

  Free water bottles are a thing now. It seems like someone at every conference, fitness class, or speaker series is handing you a bottle the second you walk in. Sure, it’s a nice perk, and you get something to drink while you’re dozing off in your chair. But have you ever considered what on Earth (literally) happens to these bottles once you’re done guzzling that water?   Chances are, those free water bottles are made of polyethylene terephthalate (PET), a type of polyester fabric. While PET isn’t great for the environment--it’s costly to produce, made from crude oil, and uses up a lot of energy to manufacture--it does have one great quality: it’s highly recyclable. rPET is the recycled version of your average water bottle, and, like a new iOS, it’s incredibly better than its PET predecessor in a multitude of ways.   Way more eco-friendly, rPET is like a second chance for synthetic materials. A second chance toward reducing landfills, lowering PET’s carbon footprint, and...

Recycling is a complicated system dictated by market demand, price determinations, local regulations, the success of which is contingent upon everyone, from the product-designer, to the trash-thrower, to the waste collector, to the recycling factory worker. We consumers play a much more critical role than we might imagine-- depending on how we use our products and in what shape we throw them away, determines their value and quality post-use....   For many, environmentalism begins with the recycling symbol and ends at the recycling bin. The simple act of throwing something away into a large box marked with a recycling sign is enough to make some of us feel like we've done our part.   It's like eating only half of a chocolate chip cookie- we indulge, but not that much. Similarly, our faith in the magic of the recycling bin makes purchasing and using plastic products a little more guilt-free.   But recycling is a lot more complicated, and the process of recycling plastics is...
