Aluminium mask plates:


- Standard mask size is 6x6 inch. Enquire for other sizes
- Standard substrate is Schott Borofloat33 for thickness 0.7, 1.1, 1.75mm
- Optical density >5.0
- Available with or without photoresist

Available with different coating options:

- Standard reflective Aluminium
    Glass side reflection: approx 90%
    Aluminium Surface side reflection: approx 90%
    Etchable to high resolution

- Medium matted hardened Aluminium
    Glass side reflection: approx 90%
    Aluminium surface side reflection: 20-50%
    The matting reduces reflections by spreading the reflected light
    Etchable to medium resolution
    Durable

- Heavy matted hardened Aluminium
    Glass side reflection: approx 90%
    Aluminium surface side reflection : <=10%
    The matting reduces reflections by spreading the reflected light
    Etchable to medium resolution
    Durable, almost vandalproof

- Forward black hardened Aluminium
    Glass side reflection: approx 90%
    Aluminium surface side reflection : <=10%
    The dark blue surface reduces reflections by absorption
    The coating has maximum absorption at approx 620nm
    Etchable to medium resolution
    Durable

- Forward matted black hardened Aluminium
    Glass side reflection: approx 90%
    Aluminium surface side reflection : <=1%
    The black matting reduces reflections by both spreading and absorbing the reflected light
    Etchable to medium resolution
    Durable

- Reverse black Aluminium
    Glass side reflection : <8%
    Aluminium surface side reflection: approx 90%
    The dark blue surface at the glass side reduces reflections by absorption.
    The coating has maximum absorption at approx 620nm
    Etchable to high resolution

- Reverse black hardened Aluminium
    Glass side reflection : <8%
    Aluminium surface side reflection: approx 90%
    The dark blue surface at the glass side reduces reflections by absorption.
    The coating has maximum absorption at approx 620nm
    Etchable to medium resolution

- Reverse black enhanced Aluminium
    Glass side reflection : <8%
    Aluminium surface side reflection :
    >92% for enhacement2 stack, >94% for enhancement4 stack at 550nm
    The dark blue surface at the glass side reduces reflections by absorption.
    The coating has maximum absorption at approx 620nm
    Not etchable with Aluminium etchant, only with HF or laser abalation
