HalfMirror
[Half mirror coat]
General mirrors widely used in washstands, etc. include total reflection mirrors
A coat (which does not transmit light) is deposited. On the contrary
Some have the function of transmitting and reflecting incident light at a certain rate
Half mirror coat.
[Type and application of half mirror coat]
In general, a dielectric multilayer film or a metal film is used for a half mirror coating. In addition to these, we use dielectric films and metal films. Hybrid half mirrors that combine these can also be deposited.
Half mirrors are used for magic from precision optical equipment such as cameras. There is a wide range of things like mirror windows, We propose the most suitable film type according to your application and request.
Types and characteristic of Half Mirror
Dielectric HM / Metal HM / Hybrid HM
Metal HM is a metal single layer film such as chromium.
Controls transmission and reflection characteristics. Most metals are deposited
In addition to glass, it does not require substrate heating.
Films can be formed on ticks. However, light absorption in the film
Light utilization efficiency (total of transmittance and reflectance) is 100%
It will not be.
On the other hand, the dielectric HM is a laminate of a plurality of dielectric films,
The cost is higher than that of metal HM.
Light absorption is very small and light utilization efficiency is almost 100%.
Hybrid HM is a combination of metal film and dielectric film.
It is possible to realize various characteristics by taking advantage of both characteristics.
Gradient HM
The characteristics of metal HM whose transmittance and reflectance change depending on the film thickness.
By utilizing the thickness gradient of one substrate
Among them, the one that realizes arbitrary transmission / reflectance distribution.This is Ent HM.
Special Magic Mirror
If HM is placed between two rooms, from one room The scenery behind the HM and the near side reflected by the HM The scenery can be seen overlapping. Dielectric HM and metal HM surface ・ The reflectance on the back is almost the same, but the difference of brightness on both sides is large. If there is a difference, the view from the other side is seen from a dark room It looks good, but the front view is reflected from the bright room I can't see the scenery on the other side. Like this, from one side It is the magic mirror that makes the other side look clearer.
On the other hand, special magic that is a kind of hybrid HM The mirror has only zero reflectance on one side, It works well even when both rooms are bright.
Special magic mirror
Conventional magic mirror
Example: Komazawa Park Animal Hospital
Our high-performance magic mirror is used in the window between the waiting and treatment rooms. According to a customer request, the treatment room should not be visible from the waiting room, but the waiting room should be visible from the treatment room. In case both rooms are similar brightness, a conventional magic mirror does not work. As such, a special magic mirror is used, and the surrounding room is reflected from the waiting room, the inside of the treatment room is hardly visible from the waiting room, but the waiting room is clearly visible fr
