Double convex lenses, also known as biconvex lenses, are one of the most common types of lenses used in various optical applications. These lenses are thicker at the center and thinner at the edges, making them ideal for converging light rays to a focal point.
Hot tack testing is an essential method used to measure the strength of a heat seal as it cools, specifically in the molten or semi-molten state. This test is crucial for flexible packaging materials, as it determines the ability of packaging to maintain its integrity during the sealing process.
Optical glass prisms are fundamental components in various optical instruments, including cameras, telescopes, and binoculars. These prisms manipulate light through refraction, reflection, and dispersion, making them indispensable in both scientific and everyday applications.

Cylindrical lenses, as the name suggests, have a cylindrical shape. Unlike spherical lenses, which are uniform in curvature across their surface, cylindrical lenses have varying curvatures along different axes. This unique design addresses specific vision issues, particularly astigmatism.

Phase noise refers to the random changes in the phase of the system output signal caused by various noises in the system (such as various RF devices). It is an important index to measure the frequency stability quality of the frequency standard source (highly stable crystal oscillator, atomic frequency standard, etc.).
