Optical laborers select high-quality optical glasses, including N-BK7, Fused Silica and sapphire. Through manual and precision instrument processing, optical domes for harsh environments are produced. Optical glass domes are corrosion resistant and high-pressure resistant. They are often used in underwater photography and underwater detection, meterological station measurement and military missiles, as a protective cover to protect sensitive sensors and detection equipment. N-BK7 Domes N-BK7 has good transmittance (400nm-1550nm) in the visible and near-infrared spectrum. N-BK7 is a common optical material with low cost and high performance. The refractive index is highly consistent. There are fewer bubbles and streaks in N-BK7. N-BK7 domes are used for solar pyrgeometers to protect the detector from rain and snow. Besides, they prevent harsh environments from affecting the sensitivity of the detector. In addition to the commonly used N-BK7 Domes, RZ Optics Co., Ltd. also produces optical domes made of fused silica and sapphire. Fused Silica Domes Fused silica is often used in the ultraviolet spectrum, between 185-2500nm, with good transmittance. Fused silica has high chemical purity, corrosion resistance and high mechanical properties. It withstands temperature changes. It is not easy to deliquesce. Fused silica domes are used as a protective cover for underwater detectors and underwater robots to protect their optical imaging systems. In addition, high-precision optical domes hardly affect the imaging effect of underwater detection equipment. Sapphire Domes Sapphire is a stable infrared material, anti-corrosion and anti-deliquesce. Under the same thickness, the performance of sapphire is better than optical glass and quartz glass, but the price is slightly more expensive. Sapphire domes are often used as a protective cover for deep-sea optical imaging systems and guided missiles due to its stable chemical properties, strong pressure resistance and better capabilities of transmission. RZ Optics Co., Ltd. produces custom optical glass domes, according to your requirements. We strictly control the parameters of optical glass domes to ensure the precise design of each batch of custom optical glass domes. For more information, please contact us.

The biconvex lens is a convergent lens with two outwardly curved surfaces, which are symmetrical. Its radius of curvature is equal. The spherical aberration, coma and distortion of biconvex lenses reach the minimum. In addition to controlling laser beams in lasers, biconvex lenses are also used for optical imaging systems or other optical instruments. N-BK7 Bi-Convex Lenses N-BK7 (Equivalent Material CDGM H-K9L) is crown glass with a transmission range of visible light and near-infrared spectrum (350nm-2000nm). N-BK7 possesses excellent optical, mechanical and chemical properties and is cost- effective. N-BK7 double convex lenses are often used in various optical imaging systems. Fused Silica Bi-Convex Lenses Between 185-2500nm, fused silica biconvex lenses have good transmittance. Fused silica has stable chemical properties, high-temperature resistance, low laser damage threshold. It is suitable for laser optical systems. Silicon Bi-Convex Lenses Silicon has metallic luster and is blocked in the visible light band. It has good transmittance in the infrared band (3-5μm). As a commonly used infrared optical material, silicon has high refractive index and small dispersion. Silicon lenses are widely used in infrared missile optical systems.

Plano-convex lenses are positive focal length elements with one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optics are ideal for general purpose focusing elements. Our lenses are ideal for a variety of applications, from industrial, robotics, pharmaceutical to defense. Esco manufactures plano-convex lenses using S1-UV grade fused silica, G1 fused silica, commercial grade and BK7 optical glass. Each optic is pitch polished to provide good surface quality and excellent low-cost imaging performance for a wide range of light sources. When plano convex lenses are used for laser cutting, they are best suited for high-turnover cutting applications and when cutting thick materials. In these cases, the plano-convex lens provides a larger cut width, which allows the laser's oxygen-assisted access to cut and aid in the cut. Plano convex lenses also provide greater depth of field, which helps create tapered edges.

Plano-Concave Lenses have edges that are thicker than the center and flat on one side. Plano-concave lenses are used to expand a light beam or increase the focal length in an optical system. They are commonly used for beam expansion of high peak power pulsed lasers. The beam incident on the concave surface will be focused to a point outside the instrument. Unwanted air heating and ionization at the focal point may accompany mode disruption or material damage. To avoid this problem, the input lens should be inverted so that the concave surface is not facing the parallel beam. Material selection: optical glass, laser crystal, fused silica, anti- radiation glass, infrared and ultraviolet materials, metal materials Strict dimensional control standards custom coating Wide selection of RZ spherical lenses made of N-BK7, UVFS or CaF2 optical materials, spherical lenses made of N-BK7, UVFS or S-LAH64 optical materials, cylinders and cones (shafts) made of N-BK7 and UVFS cone) lens.

Uses： Methylamine is used as a building block for the synthesis of other organic compounds. It is on the DEA watchlist for chemical precursors because of clandestine use in manufacture of the drug MDMA (ecstasy) and methamphetamine. The HCl salt is in the form of white deliquescent crystals, and is frequently substitutable for the aq. soln. in many synthesis preparations. Methylamines are used directly as catalysts or as raw materials to produce other compounds with catalytic activity. Fuel additives are used to improve engine performance in a variety of ways. Trimethylamine is used to make paper chemicals. The manufacture of intermediates to make pharmaceuticals is one of the most diverse uses of methylamines.
