Solid wood flooring is favored by many consumers. Besides the simple texture and color, the environmental protection of solid wood flooring is a key reason for consumers. However, the deformation of solid wood flooring is also a problem that will not occur when the floor is used and maintained. Then, what aspects should we pay attention to when purchasing solid wood flooring?

Moisture content: The moisture content of solid wood flooring is the most important factor directly affecting the floor deformation. The water content of the purchased floor must be similar to the local equilibrium moisture content. When you buy a floor, you must ask the salesperson to measure the floor moisture content. The method is very simple: first determine the moisture content of the purchased floor sample in the exhibition hall, and then unpack and accept the moisture content of the purchased floor, if the moisture content is only 1% to 2% belongs to the moisture content suitable for laying floors in the area.
Wood species: There are many species of wood flooring, including imported wood, domestic materials, valuable rosewood, teak, and popular Ganmong beans, birch, manchurian ash, etc. Because of the different types of flooring, prices vary widely. . When consumers choose the type of flooring, they must choose floorings that are relatively stable and their favorite patterns and colors.
Specifications: From the standpoint of board stability, the smaller the floor size, the better the resistance to deformation. For this reason, choose a short, narrow solid wood floor to minimize the bending, twisting, scooping, shrinking, and arching of the solid wood floor. Floor experts believe that short is better than long; narrow is better than wide, and it is cheap.
Machining accuracy: After assembling 8 to 12 floors on a flat surface, observe whether the processing accuracy is smooth, smooth, and whether the tongue and groove are suitable or not by hand and eye. Should not be too loose, nor too tight.
Material: Use the eyes to see if the floor is the same material and whether the surface of the board is cracked, rotted, peeled, dead knot, bug eyes, blue stain, or other material defects. Usually, color, joints, textures, etc. do not have to be overly demanding. This is a natural property of wood. It is the chromatic, rich and varied natural texture that shows the natural qualities of solid wood flooring. It is the current fashion of home decoration in the world.
Quality of paint: After the board has been painted, it is called paint board. When picking, please pay attention to three things and three things. Third, the paint should be uniform, smooth, and smooth. Three non-paintings should be paint-free, bubble-free, and crack-free.
After-sales service: Consumers need to consider a series of issues in order to prevent unnecessary troubles while purchasing floors.

AMICI reflection prism called also roof prism or right angle roof prism,which deflects the beam through an angle of 90 degree and inverts the image. For this reason,this prism is perfect for erecting images inverted by the objectives.
We supply many types of high precision optical prisms,such as Wedge Prism,Right Angle Prism,rhombohedral prism,Dove prism,Penta prism,pyramid prism,dispersing prism,Reflection prism etc. Each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.Reflecting prisms may invert,rotate,deviate or displace a beam.dispersing prisms produce spectral separation for spectroscopic applications or for tuning a laser output.Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.Irregular-shaped or non-standard size prisms may be available by custom order.
Specification of our Amici roof prism as follow:
*Material BK7 Grade A optical glass,UV fused silica,MgF2,N-SF10 etc.
*Dimension:3-100mm.
*Dimension Tolerance +/-0.2mm
