Unsuitable plants in nine types of offices
1, oleander: can secrete a milky white liquid, long contact time will cause people to poison, causing drowsiness, mental decline and other symptoms.
2, mimosa: its body mimosine is a very toxic organic matter, the body will cause hair loss after too much contact.
3, Bauhinia: Pollen emitted by people, such as contact with people for too long, can induce asthma or cough symptoms.
4, the rose: the rich fragrance that is emitted, can cause chest discomfort, suffocation and difficulty breathing.
5, geranium: the particles emitted, such as contact with people, can make people's skin allergic and cause pruritus.
6. Tulip: The flower contains a kind of toxin. If it is exposed for too long, it will accelerate the hair loss.

9, night fragrant: in the evening will emit a lot of stimulating scent particles, smell too long, will make high blood pressure and heart disease patients dizziness, depressed discomfort, and even worse.
Right Angle Prisms are used to direct beams at 90 degrees by using hypotenuse face in total internal reflection (TIR). The right angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirror in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prisms can serve as a retro reflector, turning beams back to the original direction.
Available in sizes ranging from 3 mm to 60 mm, Right-Angle Prisms can be used to deviate a light path by 90° or 180°, depending on which surface is used as the input for the light source.
Right angle prisms are used to redirect light beams at 90 degrees. Right angle prisms are made of BK7, UVFS optical materials.
- 45-45-90 degree prisms
- Can be used as internal or external reflectors or as retro - reflector
