Have to say, this is a very good design. This is a concept of a flexible bathtub, which will be expanded by weight while adding the corresponding amount of water. This not only saves space, but also is suitable for users of various ages and weights. The bathtub is made of a special foamed plastic with high elasticity, softness and toughness. Its weight is very light, and it is less than 3kg on the wall. Compared with ordinary porcelain bathtubs, the production and transportation costs are much lower. However, there is only one thing that is currently worrying. The bathtub swells according to the weight of the water, but what about the weight of the human body? If it can be solved very well, this is indeed a good choice for environmentally-friendly and comfortable bathing in a limited space.

The transmission range of Zinc Selenide ZnSe-CVD is 0.5 - 20 µm.
ZnSe CVD used for high power CO2 laser optics at 10.6µm, for protective optics windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications (optical plane parallel windows (plates, disks, blanks), wedged windows, optical meniscus, spherical and cylindrical lenses, prisms, resonator mirrors of CO2 laser).
The refractive index is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic.
Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.
Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
