As an example, a diffraction-limited lens with an f/# of 4 and a working wavelength of 0.55µm, the cut-off spatial frequency is approximately 454lp/mm and the MTF is approximately 0.50 at the spatial frequency of 1837 lp/mm. • Manufacturing tolerances An optical system cannot perform better than its diffraction-limited MTF. Manufacturing errors and internal-reflections of optical systems can decrease the MTF values. Typical manufacturing tolerances are listed in the following table.

Seriously, what kind of massive wand ever sends an email like that to anyone?! And absolutely not from a work email address to RoF. C’mon, name and shame. This idiot is clearly out of a job already.

MTFimage quality

The Modulation Transfer Function (MTF) is an important tool to quantify the overall imaging performance of a system. MTF is a function of spatial frequency (v), which is generally in the form of line pairs per millimeter (lp/mm). Every component within the system has an associated modulation transfer function. This includes the imaging lens, sensor, electronic board, etc.

But you didn’t send it. Of course you didn’t. That would be madness. Instead, after a moment of reflection, you took a deep breath and edited out the vitriol until you ended up with something more measured.

Nothing unusual about this at US firms - every internal email has this tone.  In fact, "stop your whining and do your job" is the partners' automated response to any emails from trainees/juniors.  Any annual leave requests elicit a one-word email response of "pathetic".

Knowing the possible MTF curves and manufacturing tolerances can help optical designers more accurately predict the system performance and estimate fabrication costs of optical products.

Doubtless quite a few PRs have wanted to say the same thing to ROF on occasion, but had the wherewithal to swallow it. If you're one of them, hopefully Mr A’s unrestrained approach has provided some cathartic relief.

Last week RollOnFriday asked this PR, let’s call him ‘Mr Angry’, why we didn't get a press release until after other outlets had received the firm’s news.

Anyone else kinda on the side of the PR manager? Imagine getting some snively twerp of a journalist sending you an entitled email moaning that they weren’t given the scoop and it’s your fault.

Optical design is the process of studying application requirements and designing optical systems to meet specific needs of optical instruments. The entire system may include optics, light source, sensor, electronics boards, display device, and/or other components. The system performance is not totally dependent on the optics. Every component within the system has contributions to the overall performance of optical instruments. For creating optical specifications and designing the optical components or assemblies, designers need to have a wide knowledge of opto-electronic components such as optical receivers and light sources, know the system performance limits, in-depth understand manufacturing tolerances and fabrication costs.

In your job, at one time or another, you’ve probably been sent an email that infuriated you, and hammered out a reply that really captured your rage and disappointment.

Needless to say, his colleagues on both sides of the pond were a little surprised by his forthright style and have done quite a lot of running around to clean up the mess. They may even have written him emails which, in their first drafts at least, rivalled his own.
