Hyperion Optics is a premium supplier of photonics products including optical components, lens systems, and opto-mechanical assemblies from UV, VIS, NIR, to SWIR applications. We specialize in optical assembly manufacturing, hyp design, optical design manufacturing from rapid prototyping to volume production. Our comprehensive metrology coupled with cost-effective philosophy can help Hyperion customers obtain a competitive edge in the global market.


Right angle prism turn light through 90° by internal reflection from the hypotenuse, or 180° from two right angle surfaces. When the light incident angle is perpendicular to the right angle surfaces, the light will be reflected at the surface of glass/air interface.


When the input light is incident from hypotenuse surface, the light will be fully reflected in the glass / air interface at the right angle surfaces. The second total reflection occurs at next right angle surface.


Compared to regular reflective mirrors, right angle prism is easily to be mounted; further its reliable mechanical stress has better stability and strength. Hence right angle prisms have been considered as suitable alternatives to reflective mirrors in various applications.


Hyperion Optics supplies a range of right angle prisms to meet UV-Visible-NIR applications, with high surface quality and tight tolerance angles. Our materials selection ranges from BK7, Bak4, fused silica, ZnSe, CaF2 etc.


Material tips for your application:


For working wavelength down to 175nm or so, with low thermal expansion requirement, Fused silica is the right choice with tighter tolerance control due to its excellent mechanical stability.
For visible and NIR wavelength, N-BK7 or CDGM H-K9L is suitable and cost effective.
For infrared wavelength, ZnSe and germanium are the right material to pick up.
Calcium fluoride has relatively wide transmittance range from 0.18~8um, it is the best choice when your application covers such wide transmission range.


Hyperion Optics has full capability of processing right angle prisms based on the materials we proposed above with 3 precision levels fit your actual demand.

In my personal view, there are lots of applicants who got it approved directly by applying it themselves rather than going via an agency.
❱❱

And I agree. I have not hired any agency's services. Nor planning to. My 3rd PR rejection came in yesterday btw. But didn't have too high hopes anyways (Only 4yrs in the country, Indian, and working in a bank, and have a girl child only).
❱❱

Some engage agencies to do the work for them because the process can be pretty complex and daunting, but if you are careful and meticulous, getting it done on your own should be no problem.

If the applicant cannot figure out the application and online submission process, I'm going to guess that they're not really cut out for permanent residency anyway.

Re: Relocating from UK with partner

When you say "partner", I assume that you do not have a spouse or you have a civil union which is not recognized by Singapore. If correct, then both of you will require an employment pass to live and work in Singapore. No dependent pass available.

Second, des your partner actually have a job with an international school lined up? With the school applying for an employment pass? Because right now, and because of Covid, getting new employment passes is very difficult.

Third, it will make no difference to you whether or not your partner has an employment pass. You must get your own employment pass on your own merits.

And that brings us to fourth... that is going to be extremely difficult to do. Maybe your cyber security credentials might get you in, but the fact is, almost nobody applying as a foreigner gets a job in Singapore. Add to that the fact that IT is a sector that the gahmen reserves for local graduates and you are facing a double whammy. Your chances of getting .....

Re: Coding School for Kids

Exactly, in my opinion nothing beats real world experience. Unfortunately, in most contexts the paper qualification is what gets your foot in the door, without it it is difficult to get by on experience alone.
