Does the Shadowless Operation Lamp have a shadow
Mar 04,2022
Shadowless Operation Lamp is an optical phenomenon due to the fact that the object blocks the transmission of light and cannot pass through the darker area formed by the opaque object two.
The Shadowless Operation Lamp manufacturer tells you that the shadow is divided into umbra and penumbra. The dark area formed by the space behind the backlight of the object that is not illuminated by light at all is called the umbra area. The area around the umbra is called the penumbra.
Shadowless Operation Lamp manufacturers tell you that since the light source on the operating lamp is not a point light source, even if there are more light sources on the surgical shadowless lamp, the umbra can only disappear, and the semi-hardness still exists, but it is a relatively bright penumbra. Therefore, Shadowless Operation Lamp manufacturers tell you that the surgical shadowless lamp is not really shadowless, but can be infinitely close to shadowless.
