We have translucent and reflective type of Hybrid/Metal/PET film/Long linear scale.
It is possible to assemble the scale with reinforcement, double-sided tape etc. and mass production at China plant.
1.Hybrid (translucent/reflective)
High accuracy metal type is realized by using nickel clad material for hybrid type.

Technology highlights
- As Ni layer improves accuracy, high accuracy and high definition etching is possible.
- As it is clad structured, each metal layer is etched and difference between upper and lower aperture can be made with high accuracy
- Ref: high contrast between reflective and non- reflective.
- Ref: compared to film product, insusceptible by humidity
- Ref: reflective area more than 60% and non-reflective area less than 10%.
- Ref: minimum bar code width 0.05 is possible
2. Metal (translucent)
Metal (SUS) is processed by photo etching to make linear scale.
Technology highlights: Fine processing
- SUS304 planarity sheet for photo etching is used.
- Minimum bar code width is around 0.07（t=0.04）
- Bar pitch tolerance within ±0.002, max and min difference of bar code tolerance in the same lot within 0.02.
Technology highlights: Standard processing
- SUS304 planarity sheet for photo etching is used.
- Minimum bar code width is around 0.08（t=0.05）
- Bar pitch tolerance within ±0.003, max and min difference of bar code tolerance in the same lot within 0.04.
3. PET film (translucent/reflective)
Fine pattern is printed on the PET film base to make linear scale.
Assembly with reinforcement, double-sided tape etc. is also available.
Technology highlights
- High precision parts of minimum bar code width 0.01(pitch 0.02) is possible.
- Achievable bar pitch tolerance within±0.002, bar code tolerance within0.005
- Rate of change by temperature 1x 10-3%/℃.
- Rate of change to relative humidity 1% is 1x 10-3%.
- Aluminum deposition for reflective type. Reflective rate 60%.
4. Long linear scale
We make translucent and reflective type of long linear scale made of PET
film.
Achievable code area is Max 3m or more.
