Standard Beamsplitter Cube
Broadband Non-Polarizing Beamsplitter Cube`s hybrid coating has certain absorption but minimal polarization sensitivity. Due to the metallic nature of the hybrid coating, those cubes are not intended for use with high powerlasers.

2. (Melon) Thrips: Adults can fly well, but they can also spread by the wind. At the same time, their reproduction speed is extremely fast. Therefore, they are prone to disasters. The climatic conditions of high temperature and low humidity are particularly suitable for their damage. The quail horses tend to be tender and tend to focus on the backs and tenders. Pharmacological control options: 5% Ruigente suspension 2000 times or 70% of the Aileen or 20% Ayurveda 5000 times and so on, alternating use, continuous spray 2 to 3 times.
3, Gualou: The insect is generally intermittent in the hot season, mainly melons (such as watermelon, loofah, etc.) of the melon leaves and melon, commonly known as "plankton." The larva body has two distinct white dorsal lines on its back. Chemical control: Select 5% Ruijinte 1000 ~ 1500 times for even and thorough spray, with good control effect.
4, nocturnal insect pests (Spodoptera exigua, Spodoptera litura): the prevention and control of nocturnal moth insect pests are generally based on stomach poisoning, so the spray must be thoughtful, the amount of water spray should be sufficient, and medication in the young age. The control agent can be used for 15% 4% hits or 20% worms dead 800 times, etc., and it can be used as a good ovicidal agent when mixed with Wanling or Fu Rui.
A Standard Beamsplitter Cube is independent of polarization. The incoming light should be: 45°linearly polarized, circularly polarized or natural light. The outgoing beams are two partially polarized beams of about the equal intensities.
Polarizing Beamsplitter Cube
A polarizing beamsplitter cube consists of two right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating. When circularly polarized or natural light enter the cube vertically, it separated into two linearly polarized beams. The transmitted beam is P-polarized while the reflected beam is S-polarized.
And when a linearly polarized light come in, it similarly divided into two beams. But the energy ratio of the two outgoing beams is depending on the polarization of the incident beam. Polarizing beamsplitter cubes are available for many laser wavelengths and broadband ranges.
Non-Polarizing Beamsplitter Cube
These cubes split the energy with minimal polarization sensitivity. The polarization states are about the same for the entrance and exit beams.
Occurrence and Control Measures of Watermelon Pests in High-temperature Seasons
1. Starscream (Cucumber Leafhopper): Starscream is a kind of hi-temperature and low-humidity pest. In March-April, we usually feed on weeds or other hosts. In the first half of May, we began to move into the hazards of melon fields. In June, the breeding rate began to increase, and the number rose to the end of June. The damage was most serious. Control agents can be used: 50% Torque 3000 ~ 4000 times or 20% of fruit 1500 times special or 1% of insects killing star 1500 times spray.
