What Are Prism Tape Sheets?
Prism Tape Sheets Are Devices That Refract Light
Prism Tape Sheets are one of the optical devices and are used to change the angle of light from a light source or to diffuse directional light. The prism sheet is made from an acrylic sheet with periodic grooves on the surface. When light is transmitted through a sheet shaped like this, the light is refracted at a certain angle. So you can change the angle of light.
Light Can Also Be Diffused by Changing the Direction of the Sheet.
When directional light is incident from the side where no grooves are dug, light exiting the Prism Tape Sheets comes out from various angles depending on the shape of the grooves. Therefore, light can be diffused by transmitting through the sheet.
Uses of Prism Tape Sheets
Prism Tape Sheets Are Used in Cell Phones and Displays.
Prism Tape Sheets are used in cell phones and TV displays. They are attached to the light path of a device's backlight to change the angle of light and increase its diffusion. Prism Tape Sheets can be used to brighten the brightness of a display by focusing the backlight.
Some Prism Tape Sheets Combine Both Functions and Reduce the Number of Device Layers.
Some Prism Tape Sheets have the dual functions of increasing luminance and diffusing light.
Features of Prism Tape Sheets
Refraction and Diffusion Behavior Changes Depending on the Direction of Light Into the Prism Tape Sheets.
Prism Tape Sheets are made from thin acrylic sheets. The surface is periodically grooved to a certain depth and shape. Refraction of light occurs when light is allowed to pass through these shaped Prism Tape Sheets. When light is applied from the grooved side of the prism, the light passes through at a constant angle of refraction. On the other hand, if the prism is not grooved and light is applied from the flat side, the light will come out from the grooved side at various angles. As a result, the light becomes diffused. In this way, the behavior of transmitted light changes greatly depending on the direction in which light enters the prism sheet, so it is necessary to check the direction of the sheet when using it.
When Using Prism Tape Sheets, Be Careful of Contact With Organic Solvents, Scratches, and Dirt.
Prism Tape Sheets are made of acrylic, and if they come into contact with organic solvents, they will swell and dissolve, losing their original function. Rubbing or applying friction to the sheet may change the shape of the grooves or damage the sheet, resulting in unnecessary light refraction and scattering. In addition, when the sheet surface is touched with bare hands, the refraction behavior may change due to the skin oils of the fingers.
Photography with Prism Tape Sheets
As mentioned above, Prism Tape Sheets change the angle of light emitted from a light source and diffuse light.
Here, we will introduce an interesting application of Prism Tape Sheets for photography, although it is different from the usual use. White light passing through a prism produces a rainbow-like spectrum due to the wavelength dependence of the refractive index.
This phenomenon, which you may have seen in junior high school science textbooks, can also be applied to photography.
Suppose you are taking portraits in the city at night. While it is of course important to capture a beautiful image of the subject illuminated by the street light, let's add a little playfulness by placing Prism Tape Sheets in front of the camera.
This will create a rainbow-like spectrum that overlaps with the subject, resulting in a fantastic photo.
