Contains harmful ion fertilizers: ammonium chloride, potassium chloride fertilizer, contains a lot of harmful chloride ions, which are applied to the soil to produce water-soluble compounds, which will burn and burn seedlings; ammonium nitrate, potassium nitrate and other fertilizers, containing nitrate ions, Seed germination has a serious impact, so it should not be used as a seed fertilizer.
Fertilizers containing toxic effects: Urea contains about 2% of diuretic urine, which can cause toxic effects on seeds and seedlings. Moreover, urea molecules with high nitrogen content also infiltrate into the molecular structure of the seed protein to denature the protein and poison the seeds and radicles.
Contains volatile and corrosive fertilizers: ammonium bicarbonate, ammonia, etc., with strong volatility, easy to smear seeds and seedlings. Calcium contains more than 5% of free sulfuric acid and phosphoric acid, which may cause damage to seed germination and seedling growth. It is generally not suitable for seed fertilizer.

Large Wedge Windows greatly reduce or eliminate interference effects caused by multiple reflections between front and rear surfaces of Plane Windows.
They are well suited for use as substrates for laser output couplers in which the reflection from the second surface must be completely eliminated from the gain medium of very sensitive lasers.
Large Wedge Windows are also known as Interferometer Flats. A pair of identical wedges are used to create an adjustable beam steering device.
Round, square, and rectangular windows are available
